Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 25, 2023The c.791G>A (p.R264Q) alteration is located in exon 5 (coding exon 5) of the VWA5B2 gene. This alteration results from a G to A substitution at nucleotide position 791, causing the arginine (R) at amino acid position 264 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
