Genes affected
SEZ6 (HGNC:15955): (seizure related 6 homolog) The protein encoded by this gene is thought to contain five cysteine-rich motifs that are similar to sushi domains, as well as two domains similar to the amino terminal half of the CUB (for complement C1r/C1s, Uegf, Bmp1) domain. Mutations in this gene have been associated with febrile seizures. [provided by RefSeq, Jul 2016]
PIPOX (HGNC:17804): (pipecolic acid and sarcosine oxidase) Enables L-pipecolate oxidase activity and sarcosine oxidase activity. Involved in L-lysine catabolic process to acetyl-CoA via L-pipecolate. Located in peroxisome. [provided by Alliance of Genome Resources, Apr 2022]
