Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2022The c.140G>A (p.G47D) alteration is located in exon 3 (coding exon 2) of the VWA5B1 gene. This alteration results from a G to A substitution at nucleotide position 140, causing the glycine (G) at amino acid position 47 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
