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]

Computational evidence support a benign effect (BayesDel_noAF=-0.68).
BP6
Variant 17-17794889-C-T is Benign according to our data. Variant chr17-17794889-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 196529.
BP7
Synonymous conserved (PhyloP=0.032 with no splicing effect.
BS1
Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.000374 (57/152228) while in subpopulation NFE AF = 0.00075 (51/68036). AF 95% confidence interval is 0.000585. There are 0 homozygotes in GnomAd4. There are 24 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
BS2
High AC in GnomAd4 at 57 AD gene.
