Genes affected

RELN (HGNC:9957): (reelin) This gene encodes a large secreted extracellular matrix protein thought to control cell-cell interactions critical for cell positioning and neuronal migration during brain development. This protein may be involved in schizophrenia, autism, bipolar disorder, major depression and in migration defects associated with temporal lobe epilepsy. Mutations of this gene are associated with autosomal recessive lissencephaly with cerebellar hypoplasia. Two transcript variants encoding distinct isoforms have been identified for this gene. Other transcript variants have been described but their full length nature has not been determined. [provided by RefSeq, Jul 2008]

The c.5005A>C (p.S1669R) alteration is located in exon 34 (coding exon 34) of the RELN gene. This alteration results from a A to C substitution at nucleotide position 5005, causing the serine (S) at amino acid position 1669 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces serine, which is neutral and polar, with arginine, which is basic and polar, at codon 1669 of the RELN protein (p.Ser1669Arg). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with RELN-related conditions. ClinVar contains an entry for this variant (Variation ID: 542571). 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 RELN protein function. 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. -
