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.9753G>C (p.E3251D) alteration is located in exon 60 (coding exon 60) of the RELN gene. This alteration results from a G to C substitution at nucleotide position 9753, causing the glutamic acid (E) at amino acid position 3251 to be replaced by an aspartic acid (D). The p.E3251D alteration is predicted to be tolerated by in silico analysis. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

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. 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. ClinVar contains an entry for this variant (Variation ID: 568369). This variant has not been reported in the literature in individuals affected with RELN-related conditions. This variant is present in population databases (rs756854888, gnomAD 0.007%). This sequence change replaces glutamic acid, which is acidic and polar, with aspartic acid, which is acidic and polar, at codon 3251 of the RELN protein (p.Glu3251Asp). -
