Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 03, 2023The c.2182G>A (p.E728K) alteration is located in exon 14 (coding exon 13) of the VWA7 gene. This alteration results from a G to A substitution at nucleotide position 2182, causing the glutamic acid (E) at amino acid position 728 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
