Multiple osteochondromas (MO) is characterised by development of two or more cartilage capped bony outgrowths (osteochondromas) of the long bones.

Most common symptoms of MULTIPLE OSTEOCHONDROMAS

  • Short stature
  • Scoliosis
  • Neoplasm
  • Failure to thrive
  • Muscle weakness

EXOSTOSES, MULTIPLE, TYPE II

Alternate names

EXOSTOSES, MULTIPLE, TYPE II Is also known as ext2

Description

Hereditary multiple exostoses is an autosomal dominant disorder characterized by multiple exostoses most commonly arising from the juxtaepiphyseal region of the long bones.

POTOCKI-SHAFFER SYNDROME

Alternate names

POTOCKI-SHAFFER SYNDROME Is also known as proximal 11p deletion syndrome, defect11 syndrome, pss, chromosome 11p11.2 deletion syndrome, 11p11.2 deletion, p11pds

Description

Potocki-Shaffer syndrome is characterized by multiple exostoses, parietal foramina, enlargement of the anterior fontanelle and occasionally intellectual deficit and mild cranio-facial anomalies. To date, 23 individuals from 14 families have been reported. The syndrome is caused by contiguous gene deletions on the short arm of chromosome 11 (11p11.2).

Most common symptoms of POTOCKI-SHAFFER SYNDROME

  • Intellectual disability
  • Seizures
  • Global developmental delay
  • Hearing impairment
  • Microcephaly

SEIZURES-SCOLIOSIS-MACROCEPHALY SYNDROME

Alternate names

SEIZURES-SCOLIOSIS-MACROCEPHALY SYNDROME Is also known as ssm syndrome

Description

Seizures-scoliosis-macrocephaly syndrome is a rare, genetic neurometabolic disorder characterized by seizures, macrocephaly, delayed motor milestones, moderate intellectual disability, scoliosis with no exostoses, muscular hypotonia present since birth, as well as renal dysfunction. Coarse facial features (including hypertelorism and long hypoplastic philtrum) and bilateral cryptorchidism (in males) are also commonly reported. Additional manifestations include abnormal gastrointestinal motility (resulting in constipation, diarrhea, gastroesophageal reflux and dysphagia), gait disturbances, strabismus and ventricular septal defects.

Most common symptoms of SEIZURES-SCOLIOSIS-MACROCEPHALY SYNDROME

  • Seizures
  • Global developmental delay
  • Generalized hypotonia
  • Scoliosis
  • Hypertelorism
