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]

Review Status:no assertion criteria provided
Collection Method:clinical testing

The RAI1 c.3589G>C variant is predicted to result in the amino acid substitution p.Gly1197Arg. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.011% of alleles in individuals of Latino descent in gnomAD, which is more common than expected for an undocumented 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.

Significance:Likely benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
