The c.263T>C (p.I88T) alteration is located in exon 2 (coding exon 2) of the SWI5 gene. This alteration results from a T to C substitution at nucleotide position 263, causing the isoleucine (I) at amino acid position 88 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
