Genes affected
CLTCL1 (HGNC:2093): (clathrin heavy chain like 1) This gene is a member of the clathrin heavy chain family and encodes a major protein of the polyhedral coat of coated pits and vesicles. Chromosomal aberrations involving this gene are associated with meningioma, DiGeorge syndrome, and velo-cardio-facial syndrome. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jun 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 08, 2024The c.4452C>G (p.I1484M) alteration is located in exon 29 (coding exon 29) of the CLTCL1 gene. This alteration results from a C to G substitution at nucleotide position 4452, causing the isoleucine (I) at amino acid position 1484 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
