The c.992G>A (p.R331Q) alteration is located in exon 9 (coding exon 9) of the NCBP3 gene. This alteration results from a G to A substitution at nucleotide position 992, causing the arginine (R) at amino acid position 331 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
