The c.973C>T (p.R325C) alteration is located in exon 1 (coding exon 1) of the HCAR2 gene. This alteration results from a C to T substitution at nucleotide position 973, causing the arginine (R) at amino acid position 325 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
