Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_174952.3(STPG2):c.995A>G(p.Tyr332Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000194 in 1,600,314 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Y332H) has been classified as Uncertain significance.

May 25, 2022

The c.995A>G (p.Y332C) alteration is located in exon 8 (coding exon 8) of the STPG2 gene. This alteration results from a A to G substitution at nucleotide position 995, causing the tyrosine (Y) at amino acid position 332 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
