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]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.038413078).

BS1

Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.0000591 (9/152192) while in subpopulation AMR AF= 0.000523 (8/15284). AF 95% confidence interval is 0.00026. There are 0 homozygotes in gnomad4. There are 8 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAd4 at 9 AD gene.

The RAI1 c.3895G>A variant is predicted to result in the amino acid substitution p.Asp1299Asn. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.014% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/17-17700157-G-A). Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
