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]

ACMG classification

Verdict is Benign. Variant got -13 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.003557533).
• BP6: Variant 11-104891260-C-T is Benign according to our data. Variant chr11-104891260-C-T is described in ClinVar as [Benign]. Clinvar id is 3056983.Status of the report is no_assertion_criteria_provided, 0 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00918 (1395/151946) while in subpopulation AFR AF= 0.0285 (1183/41464). AF 95% confidence interval is 0.0272. There are 17 homozygotes in gnomad4. There are 680 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 17 AR gene
