Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 09, 2021The c.940C>T (p.R314W) alteration is located in exon 6 (coding exon 6) of the VWA5B2 gene. This alteration results from a C to T substitution at nucleotide position 940, causing the arginine (R) at amino acid position 314 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
