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 GeneticsApr 01, 2024The c.2359C>A (p.P787T) alteration is located in exon 12 (coding exon 12) of the SEZ6 gene. This alteration results from a C to A substitution at nucleotide position 2359, causing the proline (P) at amino acid position 787 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
