Genes affected

CASP12 (HGNC:19004): (caspase 12 (gene/pseudogene)) Caspases are cysteine proteases that cleave C-terminal aspartic acid residues on their substrate molecules. This gene is most highly related to members of the ICE subfamily of caspases that process inflammatory cytokines. In rodents, the homolog of this gene mediates apoptosis in response to endoplasmic reticulum stress. However, in humans this gene contains a polymorphism for the presence or absence of a premature stop codon. The majority of human individuals have the premature stop codon and produce a truncated non-functional protein. The read-through codon occurs primarily in individuals of African descent and carriers have endotoxin hypo-responsiveness and an increased susceptibility to severe sepsis. Several alternatively spliced transcript variants have been noted for this gene. [provided by RefSeq, Feb 2011]

CASP12 (HGNC:):

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.14522417 fraction of the gene. Cryptic splice site detected, with MaxEntScore 10, offset of 0 (no position change), new splice context is: cacGTaagt. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.
• PM2: Very rare variant in population databases, with high coverage
• BP6: Variant 11-104890373-C-C is Benign according to our data. Variant chr11-104890373-C-C is described in ClinVar as [Benign]. Clinvar id is 402491.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
