Genes affected
UPK1A (HGNC:12577): (uroplakin 1A) The protein encoded by this gene is a member of the transmembrane 4 superfamily, also known as the tetraspanin family. Most of these members are cell-surface proteins that are characterized by the presence of four hydrophobic domains. The proteins mediate signal transduction events that play a role in the regulation of cell development, activation, growth and motility. This encoded protein is found in the asymmetrical unit membrane (AUM) where it can complex with other transmembrane 4 superfamily proteins. It may play a role in normal bladder epithelial physiology, possibly in regulating membrane permeability of superficial umbrella cells or in stabilizing the apical membrane through AUM/cytoskeletal interactions. The protein may also play a role in tumor suppression. Alternative splicing results in multiple transcript variants of this gene. [provided by RefSeq, Jul 2013]
UPK1A-AS1 (HGNC:40603): (UPK1A antisense RNA 1)

The c.98C>G (p.S33C) alteration is located in exon 2 (coding exon 2) of the UPK1A gene. This alteration results from a C to G substitution at nucleotide position 98, causing the serine (S) at amino acid position 33 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
