The c.316G>A (p.V106M) alteration is located in exon 6 (coding exon 4) of the CCDC7 gene. This alteration results from a G to A substitution at nucleotide position 316, causing the valine (V) at amino acid position 106 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
