The c.524A>C (p.K175T) alteration is located in exon 5 (coding exon 5) of the SIDT2 gene. This alteration results from a A to C substitution at nucleotide position 524, causing the lysine (K) at amino acid position 175 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
