To have FSHD2, an individual must inherit a mutation in the SMCHD1 gene which is located on chromosome 18 and, separately, they must inherit one copy of a "permissive" chromosome 4. Many would have had very little teaching of neuromuscular conditions in medical school and since leaving there would be little incentive to upskill unless they had a particular interest in this disease area. In cases of pelvifemoral weakness all possible causes for a limb girdle syndrome, including spinal muscular atrophy as in patient 2 might be considered, and in cases of scapula winging in the absence of facial weakness, any myopathy in which the shoulder girdle muscles are affected. Facioscapulohumeral muscular dystrophy is a disorder characterized by muscle weakness and wasting atrophy. The entire D4Z4 region is normally hypermethylated, which means that it has a large number of methyl groups consisting of one carbon atom and three hydrogen atoms attached to the DNA. The operation of scapular fixation fixing the shoulder blades to the ribs at the back has enabled some people to regain more use of their arms.
Once the diagnosis has been made you have an obligation to declare it when requested. Data from many families suggests that offspring inheriting the faulty gene are likely to be affected from a similar young age and at least as severely as occurred in their affected parent, although in large families affected daughters with FSH might be milder than their fathers. These may include protrusion of shoulder blades, known as scapular winging, difficulty throwing a ball, inability to whistle or blow up balloons , and trouble drinking from a straw.

Facio-scapulo-peroneal muscular dystrophy.
Mosaicism may explain the occurrence of severe forms in children born to parents showing no signs of the disease. More often, however, a person diagnosed with FSHD will have inherited the faulty gene from one of his or her parents. The CVS procedure is no widely available, although the tissue sample obtained would be forwarded to one of a few specialist genetic laboratories. A physical exam will show weakness of the face and shoulder muscles as well as scapular winging. As the physical toll of FSHD, our affected muscles lose their strength.

FSH muscular dystrophy is a muscle wasting condition, caused by a genetic fault, which may be affecting the regulation of the level of many of the different proteins in muscles. Sign in via OpenAthens. There is a misconception that because there are no approved drug treatments for FSHD then there is nothing you can do. FSHD is commonly associated with progressive weakening of facial, shoulder and upper arm muscles.
