Preferred Label : Cantu syndrome;
Type : Phenotype, molecular basis known;
Alternative titles and symbols : Hypertrichotic osteochondrodysplasia;
Description : Cantu syndrome is a rare disorder characterized by congenital hypertrichosis, neonatal
macrosomia, a distinct osteochondrodysplasia, and cardiomegaly. The hypertrichosis
leads to thick scalp hair which extends onto the forehead and to a general increase
in body hair. Some features are suggestive of a storage disorder, including macrocephaly
and coarse facial features, with a broad nasal bridge, epicanthal folds, wide mouth,
and full lips. About half of affected individuals are macrosomic and edematous at
birth, whereas in childhood they usually have a muscular appearance with little subcutaneous
fat. Thickened calvarium, narrow thorax, wide ribs, flattened or ovoid vertebral bodies,
coxa valga, osteopenia, enlarged medullary canals, and metaphyseal widening of long
bones have been reported. Cardiac manifestations such as patent ductus arteriosus,
ventricular hypertrophy, pulmonary hypertension, and pericardial effusions are present
in approximately 80% of cases. Motor development is usually delayed due to hypotonia.
Most patients have a mild speech delay, and a small percentage have learning difficulties
or intellectual disability (summary by van Bon et al., 2012).;
