Variant summary
Our verdict is Uncertain significance. Variant got 5 ACMG points: 5P and 0B. PM2PP2PP3_Moderate
The NM_001387283.1(SMARCA4):c.529C>G(p.Leu177Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. L177L) has been classified as Likely benign.

Rhabdoid tumor predisposition syndrome 2 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jun 27, 2022 | This variant is not present in population databases (gnomAD no frequency). 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 sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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. ClinVar contains an entry for this variant (Variation ID: 858706). This variant has not been reported in the literature in individuals affected with SMARCA4-related conditions. This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 177 of the SMARCA4 protein (p.Leu177Val). - |
