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]

Variant summary: RELN c.10276G>A (p.Val3426Ile) results in a conservative amino acid change in the encoded protein sequence. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change. The variant allele was found at a frequency of 0.0003 in 251254 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in RELN causing Epilepsy Familial Temporal Lobe 7, allowing no conclusion about variant significance. c.10276G>A has been observed in individual(s) affected with Epilepsy (Zhang_2015). These data do not allow any conclusion about variant significance. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication have been ascertained in the context of this evaluation (PMID: 26544041). ClinVar contains an entry for this variant (Variation ID: 475947). Based on the evidence outlined above, the variant was classified as uncertain significance. -
