Collection Method: clinical testing

The c.1687G>A (p.V563M) alteration is located in exon 13 (coding exon 13) of the NCBP3 gene. This alteration results from a G to A substitution at nucleotide position 1687, causing the valine (V) at amino acid position 563 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
