We performed whole-genome sequencing (WGS) in 327 children with cerebral palsy (CP) and their biological parents. We classified 37 of 327 (11.3%) children as having pathogenic/likely pathogenic (P/LP) variants and 58 of 327 (17.7%) as having variants of uncertain significance. Multiple classes of P/LP variants included single-nucleotide variants (SNVs)/indels (6.7%), copy number variations (3.4%) and mitochondrial mutations (1.5%). The COL4A1 gene had the most P/LP SNVs. We also analyzed two pediatric control cohorts (n = 203 trios and n = 89 sib-pair families) to provide a baseline for de novo mutation rates and genetic burden analyses, the latter of which demonstrated associations between de novo deleterious variants and genes related to the nervous system. An enrichment analysis revealed previously undescribed plausible candidate CP genes (SMOC1, KDM5B, BCL11A and CYP51A1). A multifactorial CP risk profile and substantial presence of P/LP variants combine to support WGS in the diagnostic work-up across all CP and related phenotypes.

Objective: This systematic review and meta-analysis aimed to assess the diagnostic yield of pathogenic or likely pathogenic (P/LP) single nucleotide variants (SNVs) using whole genome sequencing (WGS) in congenital heart disease (CHD).
Methods: A systematic search of three databases (2000-2024) was conducted, and two reviewers independently screened studies and extracted data following PRISMA and MOOSE guidelines. Pooled proportions were calculated using a random-effects model, and study quality was assessed using modified STARD criteria.

Purpose: Germ cell tumors (GCTs) are a heterogeneous group of neoplasms that predominantly affect adolescents and young adults. Notably, geographical disparities in GCT incidence exist, with higher rates observed in East Asia. Although numerous studies have established links between heterozygous germline mutations in Fanconi anemia (FA) genes and the development of certain human cancers, the association between germline pathogenic or likely pathogenic (P/LP) variants in FA genes and the relative risk of developing GCTs remains incompletely characterized.

Purpose: Genetic variation underlying rare diseases in Arab populations is poorly understood limiting effective carrier screening for recessive disorders, which are prevalent because of high consanguineous rates.
Methods: Using the American College of Medical Genetics and Genomics/Association for Molecular Pathology guidelines, we curated pathogenic (P) and likely pathogenic (LP) variants in 1333 Arab Emirati families (346 internal cohort and 987 from the literature). We also analyzed P/LP variants in 1194 Emirati exomes, calculated allele frequencies, and estimated carrier rates for the associated recessive conditions.

Identification of a pathogenic variant in NF1 is diagnostic for neurofibromatosis, but is often impossible at the moment of variant detection due to many factors including allelic heterogeneity, sequence homology, and the lack of functional assays. Computational tools may aid in interpretation but are not established for NF1. Here, we optimized our random forest-based predictor RENOVO for NF1 variant interpretation.

While ocular albinism (OA) is usually associated with reduced vision, nystagmus, and foveal hypoplasia, there is phenotypic variability in iris and fundus hypopigmentation. Hemizygous pathogenic/likely pathogenic (P/LP) variants in at X: 151.56-151.
