Variant summary

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

The NM_001390846.1(VWA5B2):c.941G>A(p.Arg314Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000838 in 1,550,536 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/20 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. R314W) has been classified as Uncertain significance.

The c.941G>A (p.R314Q) alteration is located in exon 6 (coding exon 6) of the VWA5B2 gene. This alteration results from a G to A substitution at nucleotide position 941, causing the arginine (R) at amino acid position 314 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
