The c.725T>C (p.L242P) alteration is located in exon 6 (coding exon 6) of the IAH1 gene. This alteration results from a T to C substitution at nucleotide position 725, causing the leucine (L) at amino acid position 242 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
