Variant summary
Our verdict is Likely pathogenic. Variant got 8 ACMG points: 8P and 0B. PM1PM2PP3_ModeratePP5_Moderate
The NM_000348.4(SRD5A2):c.635C>G(p.Pro212Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000109 in 1,461,634 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Synonymous variant affecting the same amino acid position (i.e. P212P) has been classified as Likely benign.

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jan 14, 2024 | This sequence change replaces proline, which is neutral and non-polar, with arginine, which is basic and polar, at codon 212 of the SRD5A2 protein (p.Pro212Arg). This variant is present in population databases (rs121434252, gnomAD 0.04%). This missense change has been observed in individuals with disorders of sex development (PMID: 8110760, 8262007, 9135696, 10718838, 10999800, 20019388). It is commonly reported in individuals of Mexican ancestry (PMID: 8110760, 8262007, 9135696, 10718838, 10999800, 20019388). ClinVar contains an entry for this variant (Variation ID: 3348). 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 expected to disrupt SRD5A2 protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects SRD5A2 function (PMID: 8110760, 24665940). For these reasons, this variant has been classified as Pathogenic. - |
