The c.409T>C (p.C137R) alteration is located in exon 4 (coding exon 4) of the IAH1 gene. This alteration results from a T to C substitution at nucleotide position 409, causing the cysteine (C) at amino acid position 137 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
