Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 27, 2024The c.2123C>T (p.A708V) alteration is located in exon 14 (coding exon 13) of the VWA7 gene. This alteration results from a C to T substitution at nucleotide position 2123, causing the alanine (A) at amino acid position 708 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
