3billion RCV003314008 SCV004013775 pathogenic Bryant-Li-Bhoj neurodevelopmental syndrome 1 criteria provided, single submitter clinical testing The variant is not observed in the gnomAD v2.1.1 dataset. The variant is located in a mutational hot spot and/or well-established functional domain in which established pathogenic variants have been reported. Missense changes are a common disease-causing mechanism. In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.46; 3Cnet: 0.83). Same nucleotide change resulting in same amino acid change has been previously reported to be associated with H3-3A related disorder (ClinVar ID: VCV001183980 / PMID: 33268356). The variant has been previously reported as de novo in a similarly affected individual (PMID: 33268356, 33268356). A different missense change at the same codon (p.Met121Lys) has been reported to be associated with H3-3A related disorder (PMID: 33268356). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline.
