Genes affected

UPK3B (HGNC:21444): (uroplakin 3B) UPK3B is a minor component of the apical plaques of mammalian urothelium that binds and dimerizes with uroplakin-1b (UPK1B; MIM 602380), one of the major conserved urothelium membrane proteins. The other major conserved integral membrane proteins of urothelial plaques are UPK1A (MIM 611557), UPK2 (MIM 611558), and UPK3A (MIM 611559) (Deng et al., 2002 [PubMed 12446744]).[supplied by OMIM, Mar 2008]

The c.266C>T (p.T89I) alteration is located in exon 1 (coding exon 1) of the UPK3B gene. This alteration results from a C to T substitution at nucleotide position 266, causing the threonine (T) at amino acid position 89 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
