The c.2219A>C (p.K740T) alteration is located in exon 19 (coding exon 19) of the CCDC175 gene. This alteration results from a A to C substitution at nucleotide position 2219, causing the lysine (K) at amino acid position 740 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
