Mutation screening of SCN2A in schizophrenia and identification of a novel loss-of-function mutation
Open accessAbstract
OBJECTIVES: There is a growing body of evidence suggesting a shared genetic susceptibility between many neuropsychiatric disorders, including schizophrenia, autism, intellectual disability (ID) and epilepsy. The sodium channel, voltage-gated type II α subunit gene SCN2A has been shown to exhibit loss-of-function (LoF) mutations in individuals with seizure disorders, ID, autism and schizophrenia. The role of LoF mutations in schizophrenia is still uncertain with only one such mutation identified to date. METHODS: To seek additional evidence for a role for LoF mutations at SCN2A in schizophrenia we performed mutation screening of the entire coding sequence in 980 schizophrenia cases. Given an absence of LoF mutations in a public exome cohort (ESP6500, N=6503), we did not additionally sequence controls. RESULTS: We identified a novel, nonsense (i.e. stop codon) mutation in one case (E169X) that is absent in 4300 European-American and 2203 African-American individuals from the NHLBI Exome Sequencing Project. This is the second LoF allele identified in a schizophrenia case to date. We also show a novel, missense variant, V1282F, that occurs in two cases and is absent in the control dataset. CONCLUSION: We argue that very rare, LoF mutations at SCN2A act in a moderately penetrant manner to increase the risk of developing several neuropsychiatric disorders including seizure disorders, ID, autism and schizophrenia.

“While most children with SCN2A variants fit into one of these three categories, there are some exceptions, including epileptic encephalopathy with choreoathetoid movements [26,27], benign infantile seizures with late-onset episodic ataxia [28–31], childhood-onset epileptic encephalopathy [32], and schizophrenia [33,34].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
