The very mild presentation in one of the patients in the present study (MCDS #51) with a single amino acid change in the a1(X) chain (1942G>A; D648N) is more likely to be the result of a dominant negative effect than of haploinsufficiency. [documents.mx]

Treatment
Since the publication of the first edition, a flurry of new disease entities has been defined and new treatment regimens have been introduced, the most spectacular being successful treatment by gene therapy for two genotypes of combined immunodeficiency [books.google.com]

The risks and the probably poor longterm prognosis were considered to markedly exceed the possible benefits of a reoperation. [documents.tips]
Non-Hodgkin lymphoma often has a poor prognosis with conventional cytotoxic protocols [ Taskinen et al 2008 ]. Endocrine. Pubertal maturation may be delayed and may require hormonal induction. [ncbi.nlm.nih.gov]
Etiology
The etiology of this rare form has not been established, but it does not result from mutations COL1A1(I) or COL1A2(I) which are the responsible disease genes for most dominant forms of OI. [nature.com]
Epidemiology
The discussion covers the phenotype spectrum, epidemiology, mode of inheritance, pathogenesis, and clinical profile of each condition, all of which is accompanied by a wealth of illustrations. [books.google.de]

Pathophysiology
Pathophysiology HME is estimated to occur in 1 in 50,000 people. It is characterized by the growth of cartilage-capped benign bone tumours around areas of active bone growth, particularly the metaphysis of the long bones. [dictionnaire.sensagent.leparisien.fr]

Pathophysiology The genetic defect in cartilage-hair hypoplasia has been identified as a mutation in the gene for RNAase RMRP, mapped to 9p12. [3, 4, 5, 6, 7, 8, 9, 52, 56] RMRP is a ribonucleoprotein present in the nucleus and mitochondria. [emedicine.medscape.com]
In rare instances autoimmune complications and a form of severe allergic reaction have been observed in CHH; however, the pathophysiology is still unknown [ Bacchetta et al 2009, Narra & Shearer 2009 ]. [ncbi.nlm.nih.gov]
