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]

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 433105). This premature translational stop signal has been observed in individual(s) with RELN-related conditions (PMID: 29358611). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Arg3326*) in the RELN gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in RELN are known to be pathogenic (PMID: 10973257, 26046367, 28454995). -
