Variant summary
Our verdict is Uncertain significance. Variant got 3 ACMG points: 4P and 1B. PM1PM2BP4
The NM_152393.4(KLHL40):āc.1493C>Gā(p.Thr498Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000743 in 1,614,034 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā ). Synonymous variant affecting the same amino acid position (i.e. T498T) has been classified as Likely benign.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Sep 07, 2022 | 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. 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 tolerated. ClinVar contains an entry for this variant (Variation ID: 577365). This variant has not been reported in the literature in individuals affected with KLHL40-related conditions. This variant is present in population databases (rs761479692, gnomAD 0.002%). This sequence change replaces threonine, which is neutral and polar, with serine, which is neutral and polar, at codon 498 of the KLHL40 protein (p.Thr498Ser). - |
