ASXL Natural History Study This registry, formerly called the ASXL Chromatin Disorders Registry/ASXL Registry, has been created to collect information about Bohring-Opitz Syndrome and ASXL related disorders in order to achieve a better understanding of these rare conditions for patients, caregivers and medical professionals. A well run registry helps produce scientific literature and leads to…
Read MoreAgain the recent publication by Urreizti et al. shows that pathogenic gene variants are part in a reference database should be taken into account. In order to assess genetic variants, reference population databases such as the Exome Aggregation Consortium (ExAC) database are part of researches. It is assumed that in this population database pathogenic gene…
Read MoreA new case report at Kagoshima City Hospital, Kagoshima, Japan describes in a newborn with Bohring-Opitz Syndrome Pulmonary Hypertension (PH).

Read MoreWe have learned that germline mutations of human ASXL1 is the cause of Bohring-Opitz syndrome (BOS). Germline means its a novo ASXL1 mutation, the gene mutates at conception, creating a developmental disorder that leads to BOS. Patients with somatic ASXL1 mutation (the mutation formed during later life) have an increased risk of myelodysplasia (MDS), myeloproliferative…
Read MoreExciting news from the ASXL Registry! Out of 33 families who have completed the enrolment, 15 surveys are completed! To obtain accurate knowledge about causes, symptoms, quality of life and treatments for Bohring-Opitz Syndrome, it is important that more families enrol the ASXL Registry and we need your support. A well run registry helps produce…
