The c.95A>C (p.Q32P) alteration is located in exon 2 (coding exon 2) of the IAH1 gene. This alteration results from a A to C substitution at nucleotide position 95, causing the glutamine (Q) at amino acid position 32 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
