The c.638A>G (p.E213G) alteration is located in exon 6 (coding exon 5) of the CCDC146 gene. This alteration results from a A to G substitution at nucleotide position 638, causing the glutamic acid (E) at amino acid position 213 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
