Variant 7-73865290-G-A details in Genebe, Genetics Data Aggregator

Variant summary

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

The ENST00000320531.3(TMEM270):c.370G>A(p.Val124Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000138 in 1,613,428 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/20 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. V124L) has been classified as Uncertain significance.

Ambry Genetics

Apr 13, 2023

The c.370G>A (p.V124M) alteration is located in exon 2 (coding exon 2) of the WBSCR28 gene. This alteration results from a G to A substitution at nucleotide position 370, causing the valine (V) at amino acid position 124 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
