Genes affected

RAI1 (HGNC:9834): (retinoic acid induced 1) This gene is located within the Smith-Magenis syndrome region on chromosome 17. It is highly similar to its mouse counterpart and is expressed at high levels mainly in neuronal tissues. The protein encoded by this gene includes a polymorphic polyglutamine tract in the N-terminal domain. Expression of the mouse counterpart in neurons is induced by retinoic acid. This gene is associated with both the severity of the phenotype and the response to medication in schizophrenic patients. [provided by RefSeq, Jul 2008]

The RAI1 c.1580G>A variant is predicted to result in the amino acid substitution p.Arg527His. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.041% of alleles in individuals of African descent in gnomAD, which may be to common to be a primary cause of disease. Although we suspect this variant may be benign, at this time its clinical significance is uncertain due to the absence of conclusive functional and genetic evidence.
