Cardioacrofacial dysplasia 1: a case report and literature review.

Translational pediatrics2026 Feb 28

Cardioacrofacial dysplasia 1 [CAFD1; Online Mendelian Inheritance in Man (OMIM): #619142] is a rare skeletal ciliopathy caused by pathogenic variants in the PRKACA gene, exhibiting phenotypic overlap with conditions such as Ellis-van Creveld (EvC) syndrome. To date, only five cases have been reported worldwide, all carrying the identical p. Gly137Arg mutation. A 10-year-old male patient presented with short stature, progressive bilateral knee deformities, post-axial posterior polydactyly, and hypoplasia of teeth and nails since infancy. He had a history of partial atrial septal defect, functional single atrium, and pulmonary valve stenosis, undergoing cardiac repair at age 5 and bilateral polydactyly resection at age 7. Whole-exome sequencing (WES) confirmed a de novo heterozygous mutation in the PRKACA gene: c.409G>A (p.Gly137Arg). At age 10, the patient underwent robot-assisted bilateral proximal tibial epiphyseal fixation. One-month postoperative follow-up demonstrated significant improvement in gait and mobility. To our knowledge, this expands the known geographic distribution with PRKACA c.409G>A (p.Gly137Arg). The finding adds to prior reports that repeatedly implicate this variant; broader ascertainment is needed to establish whether it represents a true hotspot. In patients with an EvC-like phenotype who test negative for EVC/EVC2, screening of PRKACA can be considered. Prior work suggests that increased protein kinase A (PKA) catalytic activity may dampen Hedgehog (Hh) signaling, providing a plausible mechanism for the skeletal and cardiac findings. Early molecular diagnosis facilitates multidisciplinary management and genetic counseling.

A Novel ATXN7L3 De Novo Variant Underlies Harel-Tora Neurodevelopmental Syndrome (HATONS) With Pre-Axial Polydactyly.

Clinical genetics2026 Feb 27

Cellular homeostasis is maintained by deubiquitination, which plays critical roles in DNA damage repair, cell cycle progression, signal transduction, transcriptional regulation, and autophagy. The deubiquitination (DUB) module within the Spt-Ada-Gcn5 acetyltransferase (SAGA) complex is encoded by the ATXN7L3 gene. Disease-causing variants in ATXN7L3 have been associated with an autosomal dominant neurodevelopmental disorder characterized by global developmental delay, hypotonia, speech impairment, and distinctive facial dysmorphism, known as Harel-Tora neurodevelopmental syndrome (OMIM #621377). In the present study we used whole-genome sequencing (WGS), followed by Sanger sequencing, to identify the disease-causing genetic variant. WGS identified a novel de novo nonsense variant, c.236G>A (p.Trp79*), in the exon 4 of the ATXN7L3 gene (NM_001382309.1) located on chromosome 17q21.31, segregating perfectly with the disease phenotype. Furthermore, RT-qPCR revealed a marked reduction in ATXN7L3 transcript levels in the affected individual, supporting its pathogenicity. 3D protein modeling of the mutated ATXN7L3 protein revealed substantial distortions in key secondary structural elements and loss of the C-terminal of ATXN7L3. The present study expands the mutational spectrum of the ATXN7L3 gene associated with HATONS, and helps to provide accurate genetic counseling. This will help in the management of future pregnancies within the affected family.

Bardet-Biedl syndrome presenting with early-onset infantile obesity.

BMJ case reports2026 Jan 29

Bardet-Biedl syndrome (BBS) is a rare, autosomal recessive genetic disorder. Polydactyly, obesity, pigmentary retinal degeneration, intellectual disability, kidney abnormalities and hypogonadism are common features. We report an infant who presented with obesity, micropenis, polydactyly and syndromic features, raising suspicion of a genetic syndrome. Infantile obesity is among the most common clinical findings in BBS. Whole-exome sequencing confirmed a mutation in the BBS4 gene which was homozygous and associated with BBS. The child was discharged in stable condition after 11 days of hospitalisation. On follow-up after 2 years of age, setmelanotide is planned to be initiated for his weight management. Infantile obesity, a rare and early manifestation, played a pivotal role in suspecting syndromic obesity, leading to targeted genetic investigations. The case highlights the importance of recognising early-onset obesity as a diagnostic clue for genetic syndromes by performing next-generation sequencing critical to make firm diagnosis of BBS.

Detection of the Heterozygous Recurrent MAX p.(Arg60Gln) Variant in Two Females Confirms and Expands the Phenotypic Spectrum of Polydactyly-Macrocephaly Syndrome.

Clinical genetics2026 Apr

A recurrent de novo germline variant in the MAX gene, p.(Arg60Gln), has recently been associated with polydactyly-macrocephaly syndrome in six unrelated individuals. Affected individuals presented with progressive macrocephaly, post-axial polydactyly, developmental delay, autistic features and a series of craniofacial, brain, cardiac, ocular, and renal anomalies. Here, we describe two unrelated female probands with the known recurrent MAX variant, c.179G>A p.(Arg60Gln), who presented with the emerging phenotypes of the MAX-associated syndrome. We also propose that genitourinary abnormalities, including Mayer-Rokitanski-Kuster-Hauser syndrome in one individual, may constitute an expansion of the known phenotype. These findings contribute to the current knowledge regarding the phenotypic spectrum of MAX-associated polydactyly-macrocephaly syndrome.

Molecular Landscape in Limb Anomalies: Diagnostic Yield and New Candidate Genes.

Clinical genetics2026 Mar

Congenital limb anomalies remain without an etiological diagnosis in up to 65% of patients. To help close this gap, we describe the genetic diagnostic outcomes of a large cohort. Patients whose primary indication for genetic consultation was a limb anomaly were included from 2014 to 2024. Demographic, investigation, and diagnostic information were extracted, described, and compared. One hundred and thirty-two patients were included in the final cohort, with an average molecular diagnostic yield of 36%. The most common conditions were polydactyly (24%) and radial anomalies (19%). Fifty percent had syndromic features. Seven (5%) patients underwent chromosomal microarray (CMA) only, 81 (63%) CMA and a gene panel, and 43 (32%) subsequently underwent exome sequencing. Exome yielded a diagnosis in 11 (25%). We identified 25 novel mutations in known disease-causing genes, including TBX3 (3 cases) and expanded the phenotype of several loci, including BMP4 and HNRNPH2. Finally, we identified two new limb anomalies candidate loci, for which previously published mouse studies from other groups suggested roles in limb development: HOXA11 and a 2q31.1 deletion involving HOXD10 and HOXD12. This represents the second largest described limb anomalies cohort. Exome-wide sequencing associated with literature and database searches for mouse data represents an opportunity to identify novel etiologies in this group of disorders, including two candidate loci we identified.
