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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 22, 2023The c.4552A>T (p.N1518Y) alteration is located in exon 29 (coding exon 29) of the CLTCL1 gene. This alteration results from a A to T substitution at nucleotide position 4552, causing the asparagine (N) at amino acid position 1518 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
