Variant summary
Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PM1PM2PP2PP3_StrongPP5_Moderate
The NM_000222.3(KIT):c.1747G>A(p.Glu583Lys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 12/21 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★). Synonymous variant affecting the same amino acid position (i.e. E583E) has been classified as Likely benign.

Likely pathogenic, criteria provided, single submitter | clinical testing | Invitae | Dec 20, 2023 | This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 583 of the KIT protein (p.Glu583Lys). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with piebaldism (PMID: 1376329, 1720553, 32220041; Invitae). ClinVar contains an entry for this variant (Variation ID: 13849). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Experimental studies have shown that this missense change affects KIT function (PMID: 1376329). This variant disrupts the p.Glu583 amino acid residue in KIT. Other variant(s) that disrupt this residue have been observed in individuals with KIT-related conditions (PMID: 24627108, 32220041), which suggests that this may be a clinically significant amino acid residue. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. - |
