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]

RELN NM_005045.3 exon 57 p.Lys3100del (c.9298_9300del): This variant has not been reported in the literature but is present in 0.2% (85/41368) of African alleles including 1 homozygote in the Genome Aggregation Database (https://gnomad.broadinstitute.org/variant/7-103495791-CCTT-C?dataset=gnomad_r3). This variant is present in ClinVar (Variation ID:198005). Evolutionary conservation and computational predictive tools for this variant are limited or unavailable. This variant represents an in-frame deletion of 1 amino acid at position 3100 and is not predicted to alter the reading frame. However, the effect of this variant on the protein is unclear. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
