Nature of Mutation
DNA sequencing using the SOLiD technique identified an A to G transition at position 437 of the Nlrp4a transcript in exon 3 of 11 total exons. Four transcripts of the Nlrp4a gene are displayed on Ensembl. The mutated nucleotide causes a threonine to alanine substitution at amino acid 44 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).
Protein Function and Prediction
The Nlrp4a gene encodes a encodes a 982 amino acid protein that is a member of the nucleotide-binding and oligomerization domain (NOD)-like receptor (NLR) family. The NLRP subfamily contains an N-terminal pyrin domain (PYD), a central NACHT or nucleotide-binding domain (NBD), and a C-terminal domain containing several leucine-rich repeats (LRRs). The numbers of LRRs can be variable in these proteins. The Uniprot record (Q8BU40) lists NLRP4a as containing 10 LRRs.   
 
The T44A change occurs in the PYD, but is predicted to be benign by the PolyPhen program.
