Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 07, 2022The c.53C>G (p.T18S) alteration is located in exon 2 (coding exon 2) of the VWA3A gene. This alteration results from a C to G substitution at nucleotide position 53, causing the threonine (T) at amino acid position 18 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
