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]

The c.4332G>C (p.Q1444H) alteration is located in exon 28 (coding exon 28) of the CLTCL1 gene. This alteration results from a G to C substitution at nucleotide position 4332, causing the glutamine (Q) at amino acid position 1444 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
