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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 12, 2023The c.95A>G (p.Q32R) alteration is located in exon 4 (coding exon 2) of the CHL1 gene. This alteration results from a A to G substitution at nucleotide position 95, causing the glutamine (Q) at amino acid position 32 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
