Genes affected
AMIGO3 (HGNC:24075): (adhesion molecule with Ig like domain 3) Predicted to be involved in brain development and heterophilic cell-cell adhesion via plasma membrane cell adhesion molecules. Predicted to act upstream of or within positive regulation of synapse assembly. Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]
RNF123 (HGNC:21148): (ring finger protein 123) The protein encoded by this gene contains a C-terminal RING finger domain, a motif present in a variety of functionally distinct proteins and known to be involved in protein-protein and protein-DNA interactions, and an N-terminal SPRY domain. This protein displays E3 ubiquitin ligase activity toward the cyclin-dependent kinase inhibitor 1B which is also known as p27 or KIP1. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2016]
GMPPB (HGNC:22932): (GDP-mannose pyrophosphorylase B) This gene is thought to encode a GDP-mannose pyrophosphorylase. The encoded protein catalyzes the conversion of mannose-1-phosphate and GTP to GDP-mannose, a reaction involved in the production of N-linked oligosaccharides. Alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Jan 2009]
