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]

CLTCL1 Gene-Disease associations (from GenCC):

• congenital insensitivity to pain with severe intellectual disability

  Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet
• multiple congenital anomalies/dysmorphic syndrome

  Inheritance: AD Classification: LIMITED Submitted by: Ambry Genetics

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.009658188).
• BP6: Variant 22-19235829-T-C is Benign according to our data. Variant chr22-19235829-T-C is described in ClinVar as Benign. ClinVar VariationId is 1230843.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.0812 is higher than 0.05.
