Variant summary

Our verdict is Pathogenic. The variant received 10 ACMG points: 10P and 0B. PM2PM5PP3_StrongPP5_Moderate

The NM_182894.3(VSX2):c.599G>A(p.Arg200Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000248 in 1,614,024 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 13/22 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R200P) has been classified as Likely pathogenic.
