Variant summary

Our verdict is Likely benign. Variant got -6 ACMG points: 0P and 6B. BP4_ModerateBS2

The NM_030665.4(RAI1):ā€‹c.3532C>Gā€‹(p.Leu1178Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000372 in 1,611,528 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā˜…ā˜…). Synonymous variant affecting the same amino acid position (i.e. L1178L) has been classified as Likely benign.

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]

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 25, 2023This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 1178 of the RAI1 protein (p.Leu1178Val). This variant is present in population databases (rs147321650, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with RAI1-related conditions. ClinVar contains an entry for this variant (Variation ID: 521264). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt RAI1 protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
