The c.773C>G (p.S258C) alteration is located in exon 7 (coding exon 7) of the NIPAL2 gene. This alteration results from a C to G substitution at nucleotide position 773, causing the serine (S) at amino acid position 258 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
