Genes affected

CRADD (HGNC:2340): (CASP2 and RIPK1 domain containing adaptor with death domain) This gene encodes a protein containing a death domain (DD) motif. This protein recruits caspase 2/ICH1 to the cell death signal transduction complex, which includes tumor necrosis factor receptor 1 (TNFR1A) and RIPK1/RIP kinase, and acts in promoting apoptosis. A mutation in this gene was associated with cognitive disability. A related pseudogene is found on chromosome 3. Alternative splicing results in multiple transcript variants.

Review Status:no assertion criteria provided

Collection Method:curation

NM_003805.3:c.509G>A in the CRADD gene has an allele frequency of 0.006 in European (Finnish) subpopulation in the gnomAD database. Functional studies demonstrate that Arg107Cys failed to induce cell death (PMID:27773430). Pathogenic computational verdict because pathogenic predictions from DANN, DEOGEN2, EIGEN, FATHMM-MKL, M-CAP, MutationAssessor, MutationTaster, REVEL and SIFT. The patient's phenotype is highly specific for CRADD gene(PMID: 27773430). Taken together, we interprete this variant as Pathogenic/Likely pathogenic. ACMG/AMP criteria applied: PS3; PP3; PP4.

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 170 of the CRADD protein (p.Arg170His). This variant is present in population databases (rs141179774, gnomAD 0.6%), and has an allele count higher than expected for a pathogenic variant. This missense change has been observed in individual(s) with "thin" lissencephaly (PMID: 27773430, 30914828). It is commonly reported in individuals of Finn ancestry (PMID: 30914828). ClinVar contains an entry for this variant (Variation ID: 372191). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Experimental studies have shown that this missense change affects CRADD function (PMID: 27773430, 30914828). For these reasons, this variant has been classified as Pathogenic.
