The c.64T>G (p.L22V) alteration is located in exon 2 (coding exon 2) of the NRBF2 gene. This alteration results from a T to G substitution at nucleotide position 64, causing the leucine (L) at amino acid position 22 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
