Variant summary

Our verdict is Benign. Variant got -11 ACMG points: 0P and 11B. BP4_ModerateBP6BS1BS2

The NM_030665.4(RAI1):c.1580G>A(p.Arg527His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000316 in 1,612,774 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R527C) has been classified as Uncertain significance.

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 (http://gnomad.broadinstitute.org/variant/17-17697842-G-A). 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. -
