The c.1273G>A (p.A425T) alteration is located in exon 5 (coding exon 5) of the KIAA0895 gene. This alteration results from a G to A substitution at nucleotide position 1273, causing the alanine (A) at amino acid position 425 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
