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.5961G>T (p.Lys1987Asn) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 9.2e-05 in 251100 control chromosomes, predominantly at a frequency of 0.0013 within the African or African-American subpopulation in the gnomAD database. The observed variant frequency within African or African-American control individuals in the gnomAD database exceeds the estimated maximal expected allele frequency for a pathogenic variant in RELN causing Epilepsy Familial Temporal Lobe 7 phenotype. c.5961G>T has been reported in the literature in one individual affected with Autism without strong evidence for causality (Silva_022). These report(s) do not provide unequivocal conclusions about association of the variant with Epilepsy Familial Temporal Lobe 7. 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: 35668055). ClinVar contains an entry for this variant (Variation ID: 287985). Based on the evidence outlined above, the variant was classified as likely benign. -
