Genes affected
CNTN6 (HGNC:2176): (contactin 6) The protein encoded by this gene is a member of the immunoglobulin superfamily. It is a glycosylphosphatidylinositol (GPI)-anchored neuronal membrane protein that functions as a cell adhesion molecule. It may play a role in the formation of axon connections in the developing nervous system. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2022The c.488C>G (p.P163R) alteration is located in exon 6 (coding exon 5) of the CNTN6 gene. This alteration results from a C to G substitution at nucleotide position 488, causing the proline (P) at amino acid position 163 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
