The c.910G>T (p.G304C) alteration is located in exon 9 (coding exon 9) of the EBNA1BP2 gene. This alteration results from a G to T substitution at nucleotide position 910, causing the glycine (G) at amino acid position 304 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
