The c.3041T>C (p.M1014T) alteration is located in exon 19 (coding exon 18) of the IGSF22 gene. This alteration results from a T to C substitution at nucleotide position 3041, causing the methionine (M) at amino acid position 1014 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
