Branchio-oto-renal syndrome. Case study. Epub Oct ISSN The branchio-oto-renal syndrome BOR is an uncommon autosomal dominant genetic disorder with variable expressivity, reduced penetrance and significant clinical dusorder intra-familial heterogeneity. It is caused by alterations in the development of the ears, kidneys and second branchial arches, a structure that in developing embryos produces neck tissue.

We hereby introduce a representative case of BOR syndrome that showed suggestive clinical findings such as preauricular holes, branchial fistulas, severe hearing loss with anatomical anomalies of the ear, and renal impairment. In what is a dominant genetic disorder case, we what is modern marketing concept a pathogenic variant in the EYA1 gene: c.

This is considered a null variant, since it causes a premature stop codon that leads to protein function loss. Given the BOR Syndrome variable expressivity, molecular diagnosis is relevant to prevent diagnostic errors, initiate familial cascade screening in order to identify affected relatives and to implement preventive measures aimed at reducing the morbidity and mortality caused by this syndrome.

Unless otherwise indicated, the data are expressed as No. Como citar este artículo. In most cases, the diseases PGD tests for are hereditarythat is to say, they can be transmitted from parents to children.

Townes-Brocks syndrome is a malformation genetic disease, is an autosomal dominant genetic disorder, with complete penetrance and highly variable expressivity. Bornstein, T. Tp63 mutations associating ectrodactily are usually located in the DNA-binding domain, as occurs in EEC syndrome, whereas AEC syndrome and other mutations without ectrodactily are mostly caused by mutations in the p63 SAM domain. The diagnosis of this disease can be performed through ultrasounds, but the molecular diagnosis offers some advantages, such as the early detection of asymptomatic individuals who carry this genetic defect, in order to perform a preventive monitoring and genetic counselling.
