Variant chr6-31766636-G-C details in Genebe, Genetics Data Aggregator

Variant summary

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

The NM_025258.3(VWA7):c.2011C>G(p.Pro671Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000682 in 1,612,960 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 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. P671R) has been classified as Uncertain significance.

The c.2011C>G (p.P671A) alteration is located in exon 14 (coding exon 13) of the VWA7 gene. This alteration results from a C to G substitution at nucleotide position 2011, causing the proline (P) at amino acid position 671 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
