American Journal of Medical Genetics Part A, EarlyView.ABSTRACT U2 small nuclear RNA auxiliary factor 2 (U2AF2) is an essential pre‐mRNA splicing factor involved in the early stages of pre‐mRNA splicing. To date, multiple individuals have been reported with predominantly heterozygous missense variants presenting intellectual disability, speech and motor delays, seizures, hypotonia, and thin or hypoplastic ...

Expanded Phenotype Associated With an Intronic PPP1R12A Variant: A Case Report and Literature Review
American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Autosomal dominant PPP1R12A‐related genitourinary and/or brain malformation syndrome is a recently described multisystem disorder caused by loss‐of‐function variants in the protein phosphatase 1 regulatory subunit 12a (PPP1R12A) gene. To date, 22 affected individuals have been reported with variable brain malformations and genitourinary ...

A Case of Multiple Mitochondrial Dysfunctions Syndrome 1 and Review of the Literature
American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Multiple mitochondrial dysfunctions syndrome 1 (MMDS1, MIM #605711) due to NFU1 gene defects is an ultra‐rare autosomal recessive inborn error of metabolism associated with reduced function of NFU1 iron–sulfur cluster (ISC) scaffold protein.

Ocular and Systemic Findings in COL2A1 and COL11A1 Stickler Syndrome
American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Stickler syndrome is most commonly caused by variants in COL2A1 and COL11A1 genes. The purpose of this study was to describe genetic variants and phenotypes in COL2A1 and COL11A1 Stickler syndrome. We performed a retrospective genotype–phenotype evaluation of COL2A1 and COL11A1 Stickler syndrome subjects. Thirty‐two subjects with COL2A1 and 13

Cerebellar Abnormalities in the Neuroimaging Spectrum of CLTC‐Related Disorder
American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Pathogenic variants in CLTC, which encodes the clathrin heavy chain involved in vesicle‐mediated trafficking in neurons, cause a rare neurodevelopmental disorder associated with variable severity of global developmental delay and intellectual disability and structural brain abnormalities. Although corpus callosum and white matter anomalies are

American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Detailed clinical phenotypes have been previously reported for 33 individuals with X‐linked HNRNPH2‐related neurodevelopmental disorder. Of these, 75% self‐reported a musculoskeletal abnormality, including hip dysplasia, scoliosis, kyphosis, lordosis, pes planus, arthritis, and missing spinous processes.

American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Progressive familial intrahepatic cholestasis (PFIC) is classically caused by biallelic pathogenic variants, yet monoallelic variants of uncertain significance (VUS) in PFIC‐associated genes are increasingly identified in children with cholestasis, creating diagnostic uncertainty.

Concurrent Germline RB1 & Mosaic TP53 in a Child With Multiple Childhood Cancers
American Journal of Medical Genetics Part A, EarlyView.ABSTRACT We report a patient with a pathogenic germline variant (PGV) in RB1 and somatic mosaicism for a pathogenic TP53 variant who developed three distinct types of childhood cancer: retinoblastoma, osteosarcoma, and myelodysplastic syndrome (MDS) before the age of 6 years.

An Adult Presentation of KIF11‐Related MCLID Syndrome: Case Report and 40‐Year Follow‐Up
American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Pathogenic variants in KIF11 are linked to autosomal dominant syndromes with microcephaly, chorioretinopathy, lymphedema, and intellectual disability (MCLID), though adult presentations remain underreported. We report a 42‐year‐old female presenting with a de novo single‐amino acid in‐frame deletion in the KIF11 gene (c.1294_1296del; p ...
