Description

This sequence change replaces asparagine, which is neutral and polar, with aspartic acid, which is acidic and polar, at codon 1238 of the KAT6B protein (p.Asn1238Asp). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt KAT6B protein function. This variant has not been reported in the literature in individuals affected with KAT6B-related conditions. This variant is not present in population databases (gnomAD no frequency).
