The c.1478A>C (p.K493T) alteration is located in exon 13 (coding exon 12) of the CCDC149 gene. This alteration results from a A to C substitution at nucleotide position 1478, causing the lysine (K) at amino acid position 493 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
