The c.1937G>A (p.G646E) alteration is located in exon 13 (coding exon 12) of the CCDC57 gene. This alteration results from a G to A substitution at nucleotide position 1937, causing the glycine (G) at amino acid position 646 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
