Genes affected

NLRP12 (HGNC:22938): (NLR family pyrin domain containing 12) This gene encodes a member of the CATERPILLER family of cytoplasmic proteins. The encoded protein, which contains an N-terminal pyrin domain, a NACHT domain, a NACHT-associated domain, and a C-terminus leucine-rich repeat region, functions as an attenuating factor of inflammation by suppressing inflammatory responses in activated monocytes. Mutations in this gene cause familial cold autoinflammatory syndrome type 2. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2013]

NLRP12 c.2833C>A Heterozygous. Heterozygous missense mutations of this gene can cause Familial cold autoinflammatory syndrome 2. The identified heterozygous variant is predicted to be a synonymous substitution with no change in the amino acid sequence but may have an unknown effect on splicing. This variant has not been reported in the literature and has rarely been reported in publicly available databases of healthy individuals. Therefore, the clinical significance of this heterozygous variant is uncertain. -
