This … (more) The p.Gln574Hisfs16 variant in the USP7 gene was identified de novo in this individual, but has not been previously reported in association with disease. This variant was absent from large population databases, including the Genome Aggregation Database (http://gnomad.broadinstitute.org/). This variant results in a 1 bp deletion, which causes a shift in the protein reading frame, leading to a premature termination codon 16 amino acids downstream. Heterozygous loss of function is an established mechanism of disease for the USP7 gene. These data were assessed using the ACMG/AMP variant interpretation guidelines. In summary, there is sufficient evidence to classify the p.Gln574Hisfs*16 variant as pathogenic for autosomal dominant USP7-related neurodevelopmental disorder based on the information above.
