The c.287A>T (p.Q96L) 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 287, causing the glutamine (Q) at amino acid position 96 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
