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.

Variant summary: CRADD c.382G>C (p.Gly128Arg) results in a non-conservative amino acid change located in the Death domain (IPR000488) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 8e-06 in 251410 control chromosomes. c.382G>C has been reported in the literature in multiple homozygous individuals affected with non-syndromic intellectual disability (e.g. Puffenberger_2012) including thin lissencephaly (e.g. DiDonato_2016). These data indicate that the variant is very likely to be associated with disease. One publication reports experimental evidence showing the variant failed to activate caspase-2-initiated apoptosis required for neuronal pruning, compared to WT in vitro, however, additional evidence is necessary to make any conclusions about its effect on disease course (e.g. DiDonato_2016). The following publications have been ascertained in the context of this evaluation (PMID: 27773430, 22279524). Two submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. One submitter classified the variant as pathogenic, and one submitter classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as pathogenic.
