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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 17, 2024The c.2893C>T (p.R965C) alteration is located in exon 16 (coding exon 16) of the SEZ6 gene. This alteration results from a C to T substitution at nucleotide position 2893, causing the arginine (R) at amino acid position 965 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
