Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 17, 2021The c.715G>A (p.V239I) alteration is located in exon 1 (coding exon 1) of the HCAR2 gene. This alteration results from a G to A substitution at nucleotide position 715, causing the valine (V) at amino acid position 239 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
