Genes affected
SEZ6L2 (HGNC:30844): (seizure related 6 homolog like 2) This gene encodes a seizure-related protein that is localized on the cell surface. The gene is located in a region of chromosome 16p11.2 that is thought to contain candidate genes for autism spectrum disorders (ASD), though there is no evidence directly implicating this gene in ASD. Increased expression of this gene has been found in lung cancers, and the protein is therefore considered to be a novel prognostic marker for lung cancer. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Aug 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2021The c.1588G>A (p.E530K) alteration is located in exon 10 (coding exon 10) of the SEZ6L2 gene. This alteration results from a G to A substitution at nucleotide position 1588, causing the glutamic acid (E) at amino acid position 530 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
