RCV004788397 | SCV005400247 | likely benign | Neurodevelopmental disorder | 2024-10-08 | criteria provided, single submitter | clinical testing | Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Likely benign. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with autosomal recessive lissencephaly 2 (Norman-Roberts type) (MIM#257320) and autosomal dominant familial temporal lobe epilepsy, 7 (ADTLE) (MIM#616436, GeneReviews). In addition, dominant negative has been suggested for autosomal dominant neurodevelopmental disorder (MONDO#0700092), RELN-related. (I) 0108 - This gene is associated with both recessive and dominant disease. (I) 0112 - The condition associated with this gene has incomplete penetrance. Penetrance is low for autosomal dominant familial temporal lobe epilepsy, 7 (ADTLE) (GeneReviews). (I) 0115 - Variants in this gene are known to have variable expressivity. Intrafamilial variability has been reported for neurodevelopmental disorder, RELN-related (PMID: 35769015). (I) 0200 - Variant is predicted to result in a missense amino acid change from alanine to threonine. (I) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0503 - Missense variant consistently predicted to be tolerated by multiple in silico tools or not conserved in placental mammals with a minor amino acid change. (SB) 0604 - Variant is not located in an established domain, motif, hotspot or informative constraint region. (I) 0710 - Another missense variant comparable to the one identified in this case has inconclusive previous evidence for pathogenicity. This alternative change (p.(Ala1823Glu)) has been reported as a VUS (ClinVar). (I) 0807 - This variant has no previous evidence of pathogenicity. (I) 0904 - Non-segregation of this variant with the phenotype under investigation has been clearly demonstrated. This variant was shown to be inherited from this individuals unaffected mother. (SB) 1007 - No published functional evidence has been identified for this variant. (I) 1205 - This variant has been shown to be maternally inherited. (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign |
