Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 25, 2022The c.222C>A (p.H74Q) alteration is located in exon 1 (coding exon 1) of the VN1R2 gene. This alteration results from a C to A substitution at nucleotide position 222, causing the histidine (H) at amino acid position 74 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
