The c.2486T>C (p.I829T) alteration is located in exon 20 (coding exon 20) of the KIAA1524 gene. This alteration results from a T to C substitution at nucleotide position 2486, causing the isoleucine (I) at amino acid position 829 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
