The c.1157T>A (p.L386Q) alteration is located in exon 10 (coding exon 9) of the CCDC63 gene. This alteration results from a T to A substitution at nucleotide position 1157, causing the leucine (L) at amino acid position 386 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
