Genes affected
SMIM27 (HGNC:31420): (small integral membrane protein 27) Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]
TOPORS (HGNC:21653): (TOP1 binding arginine/serine rich protein, E3 ubiquitin ligase) This gene encodes a nuclear protein which is serine and arginine rich, and contains a RING-type zinc finger domain. It is highly expressed in the testis, and functions as an ubiquitin-protein E3 ligase. Mutations in this gene are associated with retinitis pigmentosa type 31. Alternatively spliced transcript variants, encoding different isoforms, have been observed for this locus. [provided by RefSeq, Sep 2010]
