The c.790C>G (p.L264V) alteration is located in exon 8 (coding exon 7) of the NCAPD2 gene. This alteration results from a C to G substitution at nucleotide position 790, causing the leucine (L) at amino acid position 264 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
