Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 29, 2023The c.273C>A (p.S91R) alteration is located in exon 2 (coding exon 1) of the VWC2 gene. This alteration results from a C to A substitution at nucleotide position 273, causing the serine (S) at amino acid position 91 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
