Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 11, 2021The c.350C>T (p.T117I) alteration is located in exon 2 (coding exon 1) of the VWC2 gene. This alteration results from a C to T substitution at nucleotide position 350, causing the threonine (T) at amino acid position 117 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
