The c.176C>T (p.T59I) alteration is located in exon 3 (coding exon 3) of the IAH1 gene. This alteration results from a C to T substitution at nucleotide position 176, causing the threonine (T) at amino acid position 59 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
