Low clinical importance, Uncertain benign

(The "low clinical importance, uncertain" qualifier is assigned automatically based on the above evidence and importance scores.)

Inheritance pattern


Summary of published research, and additional commentary

Other mutations in this gene are reported to cause asphyxiating thoracic dystrophy and short rib-polydactyly syndrome in a recessive manner (when homozygous or compound heterozygous). http://www.ncbi.nlm.nih.gov/pubmed/19442771 The high allele frequency of this variant (4 out of 63 PGP + public genomes on GET-Evidence) contradicts it as having this rare pathogenic effect, and so it is presumed benign.

Allele frequency

  • T @ chr11:102988504: 4.8% (473/9770) in EVS
  • T @ chr11:102493713: 3.2% (4/126) in GET-Evidence
  • Frequency shown in summary reports: 4.8% (473/9770)
