Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1137G>C (p.W379C) alteration is located in exon 8 (coding exon 8) of the SHARPIN gene. This alteration results from a G to C substitution at nucleotide position 1137, causing the tryptophan (W) at amino acid position 379 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
