The Baffling Secrecy Inside Chloramben Unveiled
While relatively rare, with a prevalence of 0.7/100,000 live birth and only around 300 cases reported worldwide [1, 3, 6], it is mainly reported in highly consanguineous populations such as the Amish population [7]. The syndrome can be diagnosed either by ultrasonography starting from 18th week of gestation or through clinical examination right after birth [3]. Diagnosis after birth is based on clinical observation of features and symptoms described above. It is also supported by an X-ray of the skeleton, chest radiography, ECG, and echocardiography [1]. EvC is related to a group of diseases with alteration of cilia (ciliopathies). Such abnormalities are caused by mutations in the EvC genes (EVC and EVC2) found on chromosome 4p16 Chloramben [5, 8] in around two-thirds of the cases. In this paper, we report EvC syndrome in two unrelated Lebanese families both having homozygous mutations in the EVC2 gene, ""type"":""entrez-nucleotide"",""attrs"":""text"":""NM_147127.4"",""term_id"":""260763992"",""term_text"":""NM_147127.4""NM_147127.4: c.2653C>T p.(Arg885*) and ""type"":""entrez-nucleotide"",""attrs"":""text"":""NM_147127.4"",""term_id"":""260763992"",""term_text"":""NM_147127.4""NM_147127.4: c.2012_2015del (p.(Leu671*)) TAAT (p.(Leu671*)) in exons 15 and 13, respectively. While the first one has been recently reported in a Chinese patient, the latter is a newly described mutation. Informed consents were obtained from the patients' guardians. Genetic analysis was approved by the Institutional Review Board at the Instituto de Investigaciones Biom��dicas. Patients were clinically assessed by an experienced clinical geneticist.

Family 1 A two-year-old girl born to healthy, young consanguineous parents was referred to our genetics clinic at the American University of Beirut Medical Center (AUBMC) for short stature. The patient had a trial septal defect for which she underwent surgical repair. There was no family history of similar problems and the pregnancy and delivery were reportedly uneventful. Upon physical learn more examination, both height and weight were on the 10th percentiles according to CDC Growth Charts (Ht = 79?cm;
