The c.1061G>A (p.C354Y) alteration is located in exon 8 (coding exon 8) of the SHARPIN gene. This alteration results from a G to A substitution at nucleotide position 1061, causing the cysteine (C) at amino acid position 354 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
