The c.526G>A (p.A176T) alteration is located in exon 4 (coding exon 4) of the NRBF2 gene. This alteration results from a G to A substitution at nucleotide position 526, causing the alanine (A) at amino acid position 176 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
