Marfanoid (or Marfanoid habitus) is a constellation of symptoms resembling those of Marfan syndrome, including long limbs, with an arm span that exceeds the height of the individual, and a crowded oral maxilla, sometimes with a high arch in the palate, arachnodactyly, and hyperlaxity.

Signs and symptoms[edit]

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. Language and cognitive can affected in neonatal Marfan syndrome were intellectual disability exists and a hearing impairment of conductive loss due to hypermobility of ossicles or inflamed tympanic membrane and a sensorineural hearing impairment is due to the vestibular aqueduct plus cofactor symptoms of giddiness and imbalance may occur. Crowding of teeth and long or flat feet, often with hammer toes, may also be present.

Medical diagnostic criteria to differentiate Marfanoid habitus from Marfan syndrome :

Marfanoid habitus Marfan syndrome
Arm span to height ratio >1.03 >1.05
Scoliosis >5° >20°

Associated conditions[edit]

Marfanoid habitus is a connective tissue disorder which is generally associated with other syndrome such as Ehlers-Danlos syndrome,Perrault syndrome and Stickler syndrome.
