The c.848T>G (p.V283G) alteration is located in exon 5 (coding exon 5) of the ZNF282 gene. This alteration results from a T to G substitution at nucleotide position 848, causing the valine (V) at amino acid position 283 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
