The c.920A>T (p.K307M) alteration is located in exon 2 (coding exon 2) of the CCDC85A gene. This alteration results from a A to T substitution at nucleotide position 920, causing the lysine (K) at amino acid position 307 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
