The c.484C>A (p.P162T) alteration is located in exon 2 (coding exon 1) of the KIAA1958 gene. This alteration results from a C to A substitution at nucleotide position 484, causing the proline (P) at amino acid position 162 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
