The c.895G>A (p.V299M) alteration is located in exon 9 (coding exon 9) of the CCDC183 gene. This alteration results from a G to A substitution at nucleotide position 895, causing the valine (V) at amino acid position 299 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
