MedlinePlus Genetics : ⁴³ 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.People with Cantú syndrome have thick scalp hair that extends onto the forehead and grows down onto the cheeks in front of the ears. They also have increased body hair, especially on the back, arms, and legs. Most affected individuals have a large head (macrocephaly) and distinctive facial features that are described as "coarse." These include a broad nasal bridge, skin folds covering the inner corner of the eyes (epicanthal folds), and a wide mouth with full lips. As affected individuals get older, the face lengthens, the chin becomes more prominent, and the eyes become deep-set.Many infants with Cantú syndrome are born with a heart defect such as an enlarged heart (cardiomegaly) or patent ductus arteriosus (PDA). The ductus arteriosus is a connection between two major arteries, the aorta and the pulmonary artery. This connection is open during fetal development and normally closes shortly after birth. However, the ductus arteriosus remains open, or patent, in babies with PDA. Other heart problems have also been found in people with Cantú syndrome, including an abnormal buildup of fluid around the heart (pericardial effusion) and high blood pressure in the blood vessels that carry blood from the heart to the lungs (pulmonary hypertension).Additional features of this condition include distinctive skeletal abnormalities, a large body size (macrosomia) at birth, a reduced amount of fat under the skin (subcutaneous fat) beginning in childhood, deep horizontal creases in the palms of the hands and soles of the feet, and an increased susceptibility to respiratory infections. Other signs and symptoms that have been reported include abnormal swelling in the body's tissues (lymphedema), side-to-side curvature of the spine (scoliosis), and reduced bone density (osteopenia). Some affected children have weak muscle tone (hypotonia) that delays the development of motor skills such as sitting, standing, and walking. Most have mildly delayed speech, and some affected children have mild intellectual disability or learning problems.

MalaCards based summary : Cantu Syndrome, also known as hypertrichotic osteochondrodysplasia, is related to hypertrichosis and cardiomyopathy, dilated, 1o. An important gene associated with Cantu Syndrome is ABCC9 (ATP Binding Cassette Subfamily C Member 9), and among its related pathways/superpathways are Potassium Channels and Inwardly rectifying K+ channels. Affiliated tissues include heart, bone and brain, and related phenotypes are coarse facial features and thick vermilion border

Disease Ontology : ¹² An osteochondrodysplasia that is characterized by congenital hypertrichosis, neonatal macrosomia, and cardiomegaly.

GARD : ²⁰ The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs. Orpha Number: 1517 Definition Cantu syndrome is a rare disorder characterized by congenital hypertrichosis, osteochondrodysplasia, cardiomegaly, and dysmorphism. Epidemiology To date, fewer than 30 cases have been reported. Clinical description Dysmorphic features include macrocephaly and a coarse facial appearance with thick eyebrows, prominent supraorbital ridges, broad nasal bridge, anteverted nares, long and large philtrum, prominent mouth with full lips and macroglossia. Affected individuals have hypertrichosis with thick scalp hair extending onto the forehead and generalized increased body hair. Cardiomegaly is found in the majority of patients and pericardial effusions have been present occasionally. Additional findings in most patients included thickened calvarium, broad ribs and metaphyseal widening of long bones with enlarged medullary canals. Mild intellectual deficiency has been described in several patients. Etiology Most cases appear to be sporadic but a few familial cases, with predominantly autosomal dominant inheritance, have been reported.

OMIM® : ⁵⁷ 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). (239850) (Updated 05-Apr-2021)
