Holoprosencephaly 11
A form of holoprosencephaly, a structural anomaly of the brain in which the developing forebrain fails to correctly separate into right and left hemispheres. It is a genetically and clinically heterogeneous disorder with a wide spectrum of severity, ranging from alobar holoprosencephaly with severe facial abnormalities, such as cyclopia and proboscis, to mild forms that include lobar or microform holoprosencephaly, without cerebral malformations and with mild craniofacial defects. HPE11 inheritance is autosomal dominant.
Component of cohesin complex, a complex required for the cohesion of sister chromatids after DNA replication. The cohesin complex apparently forms a large proteinaceous ring within which sister chromatids can be trapped. At anaphase, the complex is cleaved and dissociates from chromatin, allowing sister chromatids to segregate. The cohesin complex may also play a role in spindle pole assembly during mitosis

Hypogonadotropic hypogonadism 6 with or without anosmia
A disorder characterized by absent or incomplete sexual maturation by the age of 18 years, in conjunction with low levels of circulating gonadotropins and testosterone and no other abnormalities of the hypothalamic-pituitary axis. In some cases, it is associated with non-reproductive phenotypes, such as anosmia, cleft palate, and sensorineural hearing loss. Anosmia or hyposmia is related to the absence or hypoplasia of the olfactory bulbs and tracts. Hypogonadism is due to deficiency in gonadotropin-releasing hormone and probably results from a failure of embryonic migration of gonadotropin-releasing hormone-synthesizing neurons. In the presence of anosmia, idiopathic hypogonadotropic hypogonadism is referred to as Kallmann syndrome, whereas in the presence of a normal sense of smell, it has been termed normosmic idiopathic hypogonadotropic hypogonadism (nIHH).

Cyclopia: Facial deformity indicating severe holoprosencephaly with imaging findings of brain: A case report.
Holoprosencephaly results from incomplete separation of the cerebral hemispheres. Cyclopia is a facial manifestation of Holoprosencephaly, characterized by a midline single orbit and proboscis. Prenatal diagnosis is done by ultrasonography and can be supplemented by MRI. This case uniquely presents ultrasound and gross morphology correlation of cyclopia in a resource limited setting, and a correlation between facial features, intra-cranial anatomy, and lifespan. We report a 39-year-old gravida 3 para 2 woman with a history of alcohol consumption who presented for her first antenatal checkup at 19 weeks of gestation. Ultrasound revealed a single lateral ventricle with fused thalami, absent orbital structures, and a midline cystic protrusion (proboscis). After thorough counseling, pregnancy was terminated, and cyclopia was confirmed on gross inspection. Karyotyping and fetal echocardiography were not done due to parental preference. Alobar holoprosencephaly, the most severe subtype, is diagnosed by identification of single ventricle and associated facial anomalies. Lobar holoprosencephaly, however, requires coronal imaging to demonstrate absence of cavum septum pellucidum and fusion of frontal horns. The severity of facial anomalies correlates with underlying brain malformations. Chromosomal anomalies, maternal diabetes, infections, and teratogenic exposures like alcohol are known risk factors. Differential diagnoses include proboscis lateralis, midline encephaloceles and frontonasal dysplasia. This case highlights the prognostic significance of facial and brain anomalies and diagnostic utility of prenatal ultrasound in diagnosing holoprosencephaly underscoring the necessity of timely prenatal visits. Definitive genomic studies were not feasible, but maternal alcohol consumption can be considered as a possible risk factor.
Phenotypic Spectrum and Chromosomal Discordance in Alobar Holoprosencephaly: A Comparative Case Series from a Tertiary Referral Center.
Holoprosencephaly (HPE) is a rare congenital malformation of the forebrain caused by incomplete midline cleavage, often accompanied by craniofacial abnormalities. The condition arises from multifactorial etiologies, including genetic, environmental, and maternal factors. Early prenatal diagnosis is essential for parental counseling, management decisions, and detection of associated anomalies. We report two cases of alobar HPE diagnosed in the third trimester by ultrasonography. The first case involved a 41-year-old primigravida at 32 weeks of gestation, with ultrasound findings of fused thalami, single ventricle, microcephaly, and hypotelorism. The fetus was delivered with severe midline craniofacial abnormalities and a normal female karyotype (46,XX). The second case involved a 41-year-old multiparous woman at 32 weeks of gestation. Ultrasound revealed fused thalami, absent falx cerebri and corpus callosum, and a proboscis. The infant presented with synophthalmia and proboscis, and karyotyping confirmed trisomy 13. Both pregnancies were terminated after counseling, and postnatal findings confirmed the prenatal diagnosis. This case series demonstrates the phenotypic and chromosomal variability within alobar HPE and underscores the diagnostic value of detailed ultrasonography combined with genetic analysis. Late detection in the third trimester limited reproductive options and highlights the importance of improved anomaly screening pathways. Early diagnosis remains crucial for comprehensive parental counselling and perinatal planning.
13q Deletion Syndrome Presenting with Lymphopenia Detected Through Newborn Screening for Primary Immunodeficiencies.
The expanded newborn screening (NBS) program in the Russian Federation, launched in 2023, includes the detection of severe forms of T- and B-cell immunodeficiencies via TREC/KREC quantification. We report a rare case of a male infant having multiple congenital anomalies and lymphopenia identified through this program. Genetic testing revealed a 25.8 Mb terminal deletion spanning 13q31.2-qter, consistent with 13q deletion syndrome. Initial NBS revealed reduced TREC levels, prompting further evaluation. The patient exhibited a complex phenotype, including central nervous system malformation (alobar holoprosencephaly), severe congenital heart disease, renal hypoplasia, limb and genitourinary anomalies, and facial dysmorphism. Postnatal complications included pneumonia, pleuritis, and chylothorax. Flow cytometry demonstrated mild T- and B-cell lymphopenia. The genomic defect was characterized using long-read third-generation sequencing, enabling precise breakpoint identification and accurate mapping of deleted genes. The deletion was confirmed via subtelomeric FISH analysis. The patient died at 7 months of age due to the progression of underlying congenital anomalies and associated complications. Our findings broaden the clinical characterization of distal 13q deletion syndrome and demonstrate the value of long-read sequencing in structural chromosomal analysis. They further highlight the difficulties of caring for neonates having complex malformations and immune dysfunction. Given the potential for both primary and secondary immune disturbances, comprehensive immunological evaluation should be considered in patients having 13q deletion syndrome to improve diagnostic accuracy and inform appropriate clinical management.
De novo inherited Xq25 deletion: hints from preimplantation genetic testing in alobar holoprosencephaly.
This study investigates the association between alobar holoprosencephaly (HPE) and de novo germline microdeletions in the Xq25 region. To develop a Preimplantation Genetic Testing for Monogenic Disorders (PGT-M) based workflow enabling high-resolution preimplantation detection of sub-Mb microdeletions, overcoming the >1 Mb resolution limit of conventional whole genome amplification(WGA) copy number variation(CNV) sequencing to identify causative Xq25 variants and prevent pathogenic microdeletion transmission. This study presents a clinical case involving a couple with an adverse obstetric history accompanied by two occurrences of HPE. Genetic analysis and counseling were performed, followed by haplotype analysis and PGT-M as interventions. The Mutated Allele Revealed by Sequencing with Aneuploidy and Linkage Analyses (MARSALA) technique was utilized as a simple, efficient, and reliable approach for PGT-M. The primary outcomes were the detection of chromosome microdeletions and the successful selection of embryos lacking Xq25 fragment microdeletions. Pregnancy outcomes, embryo development, and genetic counseling results served as secondary outcomes. We analyzed conception products using chromosome microarray analysis and performed single-nucleotide polymorphism haplotype linkage analysis on biopsy tissues amplified by WGA prior to sequencing. Chromosome abnormalities with microdeletions were identified using the PGT-M-based workflow. Embryo euploidy status was assessed using high-depth copy number variation sequencing. Among five tested blastocysts, three were euploid (two carrying a maternal mutation and one non-mutant.). Following implantation of the mutation-free euploid blastocyst, a successful pregnancy was achieved. Chromosomal karyotype and chromosome microarray analysis (CMA) analysis of mid-pregnancy amniotic fluid showed normal chromosomes and genetic content, leading to the birth of a healthy, full-term infant. This study underscores the necessity of maintaining detailed obstetric records, providing genetic counseling, and preserving nonviable fetal genetic material. By integrating the MARSALA technique with selected genetic marker-based SNP linkage analysis under the framework of PGT-M, this study established a method enabling single-cell-level preimplantation diagnosis of various chromosomal microabnormalities.
Prenatal imaging diagnosis of iniencephaly apertus associated with heterotaxy syndrome, alobar holoprosencephaly and myelomeningocele: a case report.
Iniencephaly is a predominantly lethal and rare form of neural tube defect characterized by fixed hyperextension of the head, occipital bone abnormalities, and cervical dysraphism. Its estimated incidence ranges from 0.1 to 10 per 10,000 births and is frequently associated with both neurological and non-neurological developmental anomalies. Here, we present the first documented case of iniencephaly apertus in conjunction with heterotaxy syndrome (HS), alobar holoprosencephaly (HPE) and myelomeningocele. Our report describes a 19-year-old primigravida with no significant medical history, whose ultrasound at 19 weeks of gestation identified findings consistent with iniencephaly apertus associated with alobar HPE and myelomeningocele. Fetal magnetic resonance imaging (MRI) at week 20 confirmed these findings and additionally revealed a centrally positioned liver and asplenia, consistent with HS. The pregnancy was terminated at week 21, resulting in a stillborn female with a normal 46 XX karyotype. The family did not consent to an autopsy. Here, we discuss the prenatal ultrasonographic, fetal MRI, and external macroscopic findings of this unique association. This case highlights the importance of prenatal diagnosis in decisions about pregnancy viability and opens a window for future research on factors contributing to the co-occurrence of these rare conditions.
