|  Ehlers–Danlos syndromes (EDS) are a group of rare genetic connective tissue disorders. LFS is also associated with psychopathology and behavioral abnormalities, and it exhibits a number of malformations affecting the brain and heart. Adducted thumb syndrome recessive form is a rare disease affecting multiple systems causing malformations of the palate, thumbs, and upper limbs. If you are able to go to the EDNF learning conference or a local support group meeting, you will see the wide variability. The severity of the symptoms of MFS is variable.

Both affected siblings of a Moroccan consanguineous family with LARS2 variants had low-frequency sensorineural hearing loss, marfanoid habitus, and primary ovarian insufficiency in the affected girl.


They generally occur in endocrine organs, but may also occur in endocrine tissues of organs not classically thought of as endocrine. This variant has already been reported as a homozygous variant in three other Perrault syndrome families. Because it's a genetic condition, the greatest risk factor for Marfan syndrome is having a parent with the disorder. 2018 Feb;176(2):404-408. doi: 10.1002/ajmg.a.38552. Marfan syndrome can interfere with the normal development of the ribs, which can cause the breastbone to either protrude or appear sunken into the chest.

The affected siblings were diagnosed as having Perrault syndrome with sensorineural hearing loss at low frequencies; the female proband had primary amenorrhea and ovarian dysgenesis. It is the most severe type of multiple endocrine neoplasia, differentiated by the presence of benign oral and submucosal tumors in addition to endocrine malignancies.

Benign or malignant tumors of nonendocrine tissues occur as components of some of these tumor syndromes. It was first described by Wagenmann in 1922, and was first recognized as a syndrome in 1965-1966 by E.D. The damage caused by Marfan syndrome can be mild or severe.

Arachnodactyly (long fingers), long limbs, scoliosis (curved spine), a hidden feature of bony lip growth towards vestibular aqueduct (which can be seen in an CT scan reports), and speech characteristic of imprecise articulation due to high-arched palate are all considered Marfanoid. Marfan syndrome affects men and women equally and occurs among all races and ethnic groups.

Both patients carried the homozygous variant c.1565C>A; p.Thr522Asn in exon 13 of the LARS2 gene. Sack–Barabas syndrome is an older name for the medical condition Ehlers-Danlos syndrome, vascular type.

Craniocervical instability is a medical condition where there is excessive laxity of the ligaments at the atlanto-occipital joint and the atlanto-axial joint, between the skull and the top two vertebrae.

Hypermobility, also known as double-jointedness, describes joints that stretch farther than normal.

Those with the condition tend to be tall and thin, with long arms, legs, fingers and toes. If your doctor suspects a problem, you'll likely be referred to a specialist for further evaluation.

Marfan syndrome can weaken the walls of the aorta, the main artery that leaves the heart. An aortic aneurysm occurs when a weak spot in the wall of your aorta begins to bulge (left). Check out these best-sellers and special offers on books and newsletters from Mayo Clinic.

These tissues form a framework, or matrix, for the body, and are composed of two major structural protein molecules: collagen and elastin. Homocystinuria or HCU is an inherited disorder of the metabolism of the amino acid methionine due to a deficiency of cystathionine beta synthase.

In about 25 percent of the people who have Marfan syndrome, the abnormal gene doesn't come from either parent. Each child of an affected parent has a 50-50 chance of inheriting the defective gene. Marfan syndrome is caused by a defect in the gene that enables your body to produce a protein that helps give connective tissue its elasticity and strength. However, marfanoid habitus was been considered a nonspecific feature in Perrault syndrome, but we believe that it may be more specific than considered previously. The disorder is inherited in an X-linked dominant manner, and is attributed to a missense mutation in the MED12 gene.

Symptoms may include loose joints, joint pain, stretchy velvety skin, and abnormal scar formation. Am J Med Genet C Semin Med Genet.
