La WDR35 gene (also known as IFT121) provides instructions for making a protein that is involved in the formation and maintenance of cilia, which are microscopic, finger-like projections that stick out from the surface of cells. Cilia participate in signaling pathways that transmit information within and between cells and are important for the development and function of many types of cells and tissues, including cells in the kidneys and liver and the light-sensitive tissue at the back of the eye (the retina). Cilia also play a role in the development of the bones, although the mechanism is not well understood.

La WDR35 gene (also known as IFT121) provides instructions for making a protein that is involved in the formation and maintenance of cilia, which are microscopic, finger-like projections that stick out from the surface of cells. Cilia participate in signaling pathways that transmit information within and between cells and are important for the development and function of many types of cells and tissues, including cells in the kidneys and liver and the light-sensitive tissue at the back of the eye (the retina). Cilia also play a role in the development of the bones, although the mechanism is not well understood.
The movement of substances within cilia and similar structures called flagella is known as intraflagellar transport. This process is essential for the assembly and maintenance of these cell structures. During intraflagellar transport, cells use molecules called IFT particles to carry materials to and from the tips of cilia. Each IFT particle is made up of two groups of IFT proteins: complex A and complex B. The protein produced from the WDR35 gene forms part of IFT complex A (IFT-A). During intraflagellar transport, this complex carries materials from the tip to the base of cilia.
The IFT-A complex is essential for proper regulation of the Sonic Hedgehog signaling pathway, which is important for the growth and maturation (differentiation) of cells and the normal shaping (patterning) of many parts of the body, especially during embryonic development. The exact role of the complex in this pathway is unclear.

Pneumothorax
A pneumothorax is sometimes called a "collapsed lung" and it describes the condition in which air has become trapped next to a lung. Many cases occur without warning, particularly in healthy young men. Some develop as a complication of a chest injury or a lung disease. The most common symptom is a sudden sharp chest pain followed by pains on.

Hyperplasie de l'endomètre
There are two types. The cells are all normal, however, and are very unlikely to ever change to cancer. Over time, the overgrowth of cells may stop on its own, or may need treatment to do so. Atypical hyperplasia In this type, the cells are not normal (they are said to be atypical). This type of hyperplasia is more likely to become cancerous over.

Ictère néonatal
Neonatal jaundice is very common in the first two weeks of a baby's life. It is usually harmless but may be due to a serious cause which needs treatment in hospital. Neonatal jaundice is more likely to have a serious cause if it is seen in the first 24 hours of life or doesn't disappear by 2 weeks of age. All babies with jaundice should be seen by.
