Genes affected
CNTN4 (HGNC:2174): (contactin 4) This gene encodes a member of the contactin family of immunoglobulins. Contactins are axon-associated cell adhesion molecules that function in neuronal network formation and plasticity. The encoded protein is a glycosylphosphatidylinositol-anchored neuronal membrane protein that may play a role in the formation of axon connections in the developing nervous system. Deletion or mutation of this gene may play a role in 3p deletion syndrome and autism spectrum disorders. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2011]
CNTN4-AS1 (HGNC:39985): (CNTN4 antisense RNA 1)

CNTN4-related disorder Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesMay 09, 2023The CNTN4 c.2525G>C variant is predicted to result in the amino acid substitution p.Arg842Thr. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.018% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/3-3084674-G-C). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
