The c.44T>C (p.I15T) alteration is located in exon 3 (coding exon 1) of the COX7B2 gene. This alteration results from a T to C substitution at nucleotide position 44, causing the isoleucine (I) at amino acid position 15 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
