The c.47G>T (p.G16V) alteration is located in exon 4 (coding exon 2) of the CC2D2B gene. This alteration results from a G to T substitution at nucleotide position 47, causing the glycine (G) at amino acid position 16 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
