The c.800A>C (p.K267T) alteration is located in exon 9 (coding exon 7) of the CCDC77 gene. This alteration results from a A to C substitution at nucleotide position 800, causing the lysine (K) at amino acid position 267 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
