Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 5P and 1B. PM2PM5PP5BP4

The NM_003805.5(CRADD):​c.508C>T​(p.Arg170Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000744 in 1,613,620 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R170H) has been classified as Pathogenic.

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.

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PM5
Other missense variant is known to change same aminoacid residue: Variant chr12-93850180-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 372191.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
PP5
Variant 12-93850179-C-T is Pathogenic according to our data. Variant chr12-93850179-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 372190.Status of the report is no_assertion_criteria_provided, 0 stars.
BP4
Computational evidence support a benign effect (MetaRNN=0.19620994). . Strength limited to SUPPORTING due to the PP5.
