The c.437A>G (p.E146G) alteration is located in exon 7 (coding exon 6) of the CCDC129 gene. This alteration results from a A to G substitution at nucleotide position 437, causing the glutamic acid (E) at amino acid position 146 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
