The c.1889A>T (p.K630I) alteration is located in exon 16 (coding exon 16) of the CCDC175 gene. This alteration results from a A to T substitution at nucleotide position 1889, causing the lysine (K) at amino acid position 630 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
