Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 27, 2023The c.883C>T (p.R295W) 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 883, causing the arginine (R) at amino acid position 295 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
