Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 22, 2022The c.916A>T (p.M306L) alteration is located in exon 10 (coding exon 10) of the VWA3A gene. This alteration results from a A to T substitution at nucleotide position 916, causing the methionine (M) at amino acid position 306 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
