ORPHA:562528Malformation syndrome
Also called CLIFAHDD syndrome
What it is
A rare multiple congenital anomalies/dysmorphic syndrome with intellectual disability characterized by severe congenital contractures of the limbs and face, hypotonia, neonatal respiratory distress, and global developmental delay. Dysmorphic facial features include downslanting palpebral fissures, broad nasal bridge, large nares, long philtrum, and deep nasolabial folds, among others. Limb deformities (camptodactyly, clubfoot), short neck, scoliosis, as well as seizures have also been reported. Brain MRI may show cerebral and cerebellar atrophy in some cases.

Gene
ICD-10 codes
ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
