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 Gene-Disease associations (from GenCC):

• familial cold autoinflammatory syndrome 2

  Inheritance: AD Classification: STRONG, MODERATE, SUPPORTIVE Submitted by: Labcorp Genetics (formerly Invitae), Ambry Genetics, Orphanet, Laboratory for Molecular Medicine

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PP3: MetaRNN computational evidence supports a deleterious effect, 0.877
• BS2: High AC in GnomAdExome4 at 59 AD gene.
