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.4841A>T (p.D1614V) alteration is located in exon 31 (coding exon 31) of the CLTCL1 gene. This alteration results from a A to T substitution at nucleotide position 4841, causing the aspartic acid (D) at amino acid position 1614 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
