The c.1679A>C (p.K560T) alteration is located in exon 14 (coding exon 14) of the KIAA0907 gene. This alteration results from a A to C substitution at nucleotide position 1679, causing the lysine (K) at amino acid position 560 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
