The c.19A>G (p.S7G) alteration is located in exon 2 (coding exon 1) of the CCDC171 gene. This alteration results from a A to G substitution at nucleotide position 19, causing the serine (S) at amino acid position 7 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
