Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 09, 2022The c.526G>A (p.D176N) alteration is located in exon 3 (coding exon 3) of the VWA5B2 gene. This alteration results from a G to A substitution at nucleotide position 526, causing the aspartic acid (D) at amino acid position 176 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
