Genes affected

MUC17 (HGNC:16800): (mucin 17, cell surface associated) The protein encoded by this gene is a membrane-bound mucin that provides protection to gut epithelial cells. The encoded protein contains about 60 tandem repeats, with each repeat being around 60 aa. N-glycosylation enables the encoded protein to localize on the cell surface, while the C-terminus interacts with the scaffold protein PDZ domain containing 1 (PDZK1). Two transcript variants, one protein-coding and the other non-protein coding, have been found for this gene. [provided by RefSeq, Nov 2015]

The c.920T>C (p.I307T) alteration is located in exon 3 (coding exon 3) of the MUC17 gene. This alteration results from a T to C substitution at nucleotide position 920, causing the isoleucine (I) at amino acid position 307 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
