The Stickler syndrome is a hereditary
vitreoretinopathy characterized by the association of ocular signs with more or
less complete forms of Pierre-Robin sequence (see this term), bone disease, and
deafness (10% of cases).
The incidence at birth was estimated
to be about 1/7, 500.
The eye disease may include juvenile
cataract, myopia, strabismus, vitreoretinal or corioretinal degeneration,
retinal detachment, and chronic uveitis. The skeletal anomalies include
platispondilia slight and large epiphyses, often with abnormalities. The
laxidez articulate youth is followed by early signs of arthrosis.
The syndrome is usually transmitted as
an autosomal dominant genetically heterogeneous. The type 1 Stickler syndrome
is caused by mutations in the COL2A1 gene (12q13.11-Q13.2), the type 2 Stickler
syndrome is caused by mutations in the gene COL11A1 (1p21) and Stickler syndrome
type 3 (without ocular signs; see this term) is caused by mutations in the
COL11A2 gene (6p21.3). Was also described in a Moroccan family, an autosomal
recessive form of Stickler syndrome associated with mutations in geneCOL9A1
(6q12-q14).
Diagnosis
Diagnosis is based on clinical and can
be confirmed by molecular analysis.
The prenatal diagnosis is possible for
families in which the disease causative mutation was identified.
Management should be multidisciplinary
and how the clinical expression is highly variable, the treatment needs to be
tailored to each case.
The prognosis depends on the severity
of signs present.
