Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2022The c.551A>G (p.H184R) alteration is located in exon 1 (coding exon 1) of the HCAR3 gene. This alteration results from a A to G substitution at nucleotide position 551, causing the histidine (H) at amino acid position 184 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
