Macular and optic nerve hypoplasia in chromosome 2p partial trisomy.

Ophthalmic genetics2026 Apr

The 2p duplication syndrome is a rare clinically heterogeneous disorder that arises from non-recurrent chromosomal rearrangements involving ~6 Mb up to ~90 Mb. The patients are characterized by a wide range of symptoms, including developmental delay, intellectual disability, distinctive facial features, congenital heart defects, and various ophthalmic manifestations. We report a male newborn with maternally inherited unbalanced translocations resulting in partial trisomy of chromosome 2p (33.9 Mb) - 46,XY,der(10)t(2;10)(p22.3;p1?5)dmat. Fluorescence in situ hybridization and chromosomal microarray analyses confirmed three copies of 2p25.3-p22.3 region, encompassing 51 known disease-causing genes. The patient presented with low birth weight, ventricular septal defect, camptodactyly of the 3rd digit of the left hand and mild early feeding problems. Ophthalmological assessment revealed macular and optic nerve hypoplasia. MRI demonstrated hypoplasia of the optic chiasm and optic nerves, and partial agenesis of falx cerebri. We describe macular and optic nerve hypoplasia in a patient with a novel chromosomal rearrangement resulting in 2p partial trisomy and provide an overview of 17 previously reported cases presenting ocular abnormalities. A broad variability of ophthalmological phenotypes has been observed, further expanded by the current report.

Long-Term Survival Among Children With Trisomy 13 and Trisomy 18 by Cytogenetic Status.

JAMA network open2025 Sep 02

Trisomy 13 (T13) and trisomy 18 (T18) are chromosomal abnormalities with high mortality rates in the first year of life. Understanding differences in long-term survival between children with full vs mosaic or partial trisomy is crucial for prognosis and health care planning. To examine the differences in 10-year survival between children with full T13 and T18 vs those with mosaic or partial trisomy. This retrospective, population-based cohort study assessed liveborn infants with T13 and T18 in the Texas Birth Defects Registry (deliveries from January 1, 1999, to December 31, 2008). Follow-up was through December 31, 2018 (the last date available at the time of analyses) to allow for 10 years of follow-up for all infants. All analyses were conducted from January 1, 2022, to December 31, 2024. Cytogenetic status (full trisomy vs mosaic or partial trisomy). The primary outcome was survival to 10 years of age, assessed using Kaplan-Meier survival estimates. The association between cytogenetic status and mortality by 10 years of age was assessed using Cox proportional hazards regression to generate hazard ratios (HRs). Population attributable fraction was calculated to determine the percentage of survival attributable to mosaic or partial trisomy status. The study cohort included 798 infants (463 female infants [58.0%]; mean [SD] maternal age, 30.9 [8.0] years) with T13 (n = 295) or T18 (n = 503). Among all cases with T13, 25 infants (8.5%; 95% CI, 5.5%-12.3%) survived to 10 years of age. Similarly, among all infants with T18, 43 (8.6%; 95% CI, 6.3%-11.3%) survived to 10 years of age. Kaplan-Meier survival estimates to 10 years of age were statistically significantly higher among children with mosaic or partial trisomy (13 [25.0%] and 14 [43.8%], respectively) compared with full trisomy (12 [4.9%] and 29 [6.6%], respectively) (both P < .001). Infants with full trisomy had statistically significantly increased 10-year mortality hazards compared with those with mosaic or partial trisomy for both T13 (HR, 2.00; 95% CI, 1.42-2.82) and T18 (HR, 3.34; 95% CI, 2.08-5.38). The results of the calculated proportion of 10-year survival due to the presence of nonfull trisomy status (population attributable fraction) was 41.7% for children with T13 and 27.9% for children with T18. The findings of this cohort study of infants with T13 and T18 support differences in long-term survival based on cytogenetic status and emphasize the need to potentially reassess the context of these conditions generally being considered incompatible with life, particularly for those with mosaic trisomies. These findings offer context surrounding treatment decisions, such as withholding interventions, for affected infants in the future.

Prenatal diagnosis of partial duplication chromosome 21q11.2-21q21.1: A case report and literature review.

Taiwanese journal of obstetrics &amp; gynecology2025 Sep

We report the prenatal diagnosis for a small supernumerary marker chromosome derived from chromosome 21q11.2-q21.1. A 40-year-old woman presenting at 13 weeks of gestation underwent noninvasive prenatal testing (NIPT) due to advanced maternal age. A positive finding for trisomy 21 urged genetic counseling and subsequent amniocentesis. Amniocentesis revealed a karyotype of 47, XX,+mar. The parental karyotypes were normal, and prenatal ultrasound findings were unremarkable. At a follow-up genetic counseling session, additional prenatal genetic testing was undertaken, specifically, amniocentesis including microarray-based comparative genomic hybridization (aCGH). The aCGH analysis of cultured amniocytes revealed a 1.4 MB duplication of the 21q11.2-q21.1 segment, which is not associated with Down syndrome, and the couple decided to continue her pregnancy. The infant was born without the symptoms of Down syndrome and remains to be so till six months. We thus present a clinically and genetically unique case of discordant NIPT and aCGH results.

Optical Genome Mapping in Myelodysplastic Syndromes: Clinical Value and Limitations Derived From a Cohort of 236 Patients.

Modern pathology : an official journal of the United States and Canadian Academy of Pathology, Inc2025 Oct

Identification of cytogenetic abnormalities is critical for the classification and risk stratification of myelodysplastic syndromes (MDS). Optical genome mapping (OGM) is an emerging cytogenomic platform that enables high-resolution genome-wide cytogenetic analysis. We analyzed bone marrow specimens of 236 MDS patients, 149 newly diagnosed and 87 with relapsed/refractory disease, using OGM, conventional karyotyping, and next-generation sequencing analysis. OGM and karyotyping showed concordant results in 68% of cases, including 34% with normal findings by both assays. OGM provided additional information in 27% of patients. Common abnormalities detected exclusively by OGM included chromoanagenesis (n = 33), KMT2A partial tandem duplication (n = 7), and MECOM rearrangement (n = 4). These OGM findings led to disease reclassification and/or changes in risk stratification in 14 patients (9.4%) with newly diagnosed MDS. In contrast, OGM failed to detect small clones or subclones in 5% of patients, resulting in risk group changes in 2% of newly diagnosed MDS patients. We conclude that OGM enhances the cytogenetic assessment of MDS in approximately 25% of patients and leads to a change in disease classification and/or risk stratification in approximately 10% of patients. However, low sensitivity for detecting small clones or subclones remains a limitation of OGM.

Fork Stalling and Template Switching in a Complex der(6)dn with Duplication of 6q24.3qter and 6p25.3: A Case Report.

Cytogenetic and genome research2025

Partial trisomy of the 6q24qter region is a rare chromosomal disorder characterized by variable clinical features and poorly understood mechanistic origins. We describe a de novo complex der(6) chromosome in a patient with features consistent with partial 6q trisomy syndrome, including congenital heart disease, growth restriction, developmental delay, and dysmorphic traits. Molecular Findings: Whole-genome sequencing (WGS) identified duplications of 1.5 Mb on 6p25.3 and 23.3 Mb on 6q24.3-qter. While the 6p duplication appears benign, the phenotype is likely driven by dosage-sensitive 6q genes (ARID1B, TAB2, QKI) and possible additive effects from other duplicated genes. No parental pericentric inversion was detected by classical or molecular cytogenetics, and WGS revealed no inversion-associated breakpoints. Instead, chimeric (q-/q+) and truncated reads at the 6q junction support a replication-based origin, such as reversed template switching. FISH confirmed direct insertion of the 6q segment into 6p25.3, without a del/dup pattern typical of inversion-derived recombinants. Notably, WGS detected no direct 6p-6q junction reads but identified chimeric 6p-15q-6q reads with 2-bp microhomologies, suggesting that chromosome 15 transiently mediated the rearrangement. Interspersed telomeric sequences and flanking Alu elements were also found at both breakpoints. Altogether, these findings support a model in which replication fork stalling and template switching - potentially facilitated by telomere dynamics and repetitive elements - led to the formation of a recombinant-like der(6) chromosome. This case highlights the mechanistic complexity of structural rearrangements and the role of replication-based errors in shaping human genomic variation.
