The c.1112G>A (p.G371E) alteration is located in exon 1 (coding exon 1) of the SBSN gene. This alteration results from a G to A substitution at nucleotide position 1112, causing the glycine (G) at amino acid position 371 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
