TTC7A Mutations for Combined Immunodeficiency with Intestinal Atresia

Combined Immunodeficiency with Multiple Intestinal Atresias (CID-MIA) is a rare genetic disorder with the cause previously unknown. Symptoms of CID-MIA include atresias in the small and/or large intestine, as well as immunodeficiency. In this study, we sequenced the whole exome of 5 unrelated CID-MIA patients as well as their healthy family members, and identified deleterious homozygous or compound heterozygous mutations in the gene TTC7A in all the 5 patients, as well as in 3 additional patients with Sanger sequencing. Our findings strongly indicate TTC7A dysfunction to be the cause for CID-MIA.]]>
