Genes affected

CHL1 (HGNC:1939): (cell adhesion molecule L1 like) The protein encoded by this gene is a member of the L1 gene family of neural cell adhesion molecules. It is a neural recognition molecule that may be involved in signal transduction pathways. The deletion of one copy of this gene may be responsible for mental defects in patients with 3p- syndrome. This protein may also play a role in the growth of certain cancers. Alternate splicing results in both coding and non-coding variants. [provided by RefSeq, Nov 2011]

The c.1837C>G (p.L613V) alteration is located in exon 16 (coding exon 14) of the CHL1 gene. This alteration results from a C to G substitution at nucleotide position 1837, causing the leucine (L) at amino acid position 613 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
