The c.2245G>A (p.A749T) alteration is located in exon 15 (coding exon 14) of the CCDC57 gene. This alteration results from a G to A substitution at nucleotide position 2245, causing the alanine (A) at amino acid position 749 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
