Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has been observed in individual(s) with clinical features of WDR19-related conditions (Invitae). In at least one individual the data is consistent with the variant being in trans (on the opposite chromosome) from a pathogenic variant. This variant is not present in population databases (ExAC no frequency). This sequence change replaces isoleucine with threonine at codon 489 of the WDR19 protein (p.Ile489Thr). The isoleucine residue is highly conserved and there is a moderate physicochemical difference between isoleucine and threonine. |
