MalaCards based summary: Hypertrichotic Osteochondrodysplasia, also known as cantu syndrome, is related to hypertrichotic osteochondrodysplasia cantu type and cantú syndrome and related disorders, and has symptoms including wide mouth, thick lower lip vermilion and coarse facial features. An important gene associated with Hypertrichotic Osteochondrodysplasia is ABCC9 (ATP Binding Cassette Subfamily C Member 9), and among its related pathways are Transmission across Chemical Synapses and Potassium Channels. Affiliated tissues include bone and heart.

Genetics Home Reference:24 Cantú syndrome is a rare condition characterized by excess hair growth (hypertrichosis), a distinctive facial appearance, heart defects, and several other abnormalities. The features of the disorder vary among affected individuals.

UniProtKB/Swiss-Prot:68 Hypertrichotic osteochondrodysplasia: 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 a general increase in body hair. In addition, macrocephaly and coarse facial features, including a broad nasal bridge, epicanthal folds, a wide mouth, and full lips, can be suggestive of a storage disorder. 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.
