Summaries for Tetramelic Deficiencies, Ectodermal Dysplasia, Deformed Ears, and...

NIH Rare Diseases : 53 Odontotrichomelic syndrome is a very rare ectodermal dysplasia affecting the hair, teeth, and nails and all four extremities. The main problems are malformations of all the extremities including absence of several bones in the hands and feet, abnormal teeth, and sparse hair (hypotrichosis). Other signs and symptoms may include: very small or undeveloped (hypoplastic) nails; abnormalities of the ear; excessive sweating (hyperhidrosis); an unusual facial appearance with malformed ears, large nose, high forehead, and protruding lips; as well as a flat head, long neck, and sloping shoulders with dimples on top. The cause is unknown. Inheritance is autosomal recessive. Because very few people have been described, there is no information about specific treatment.

MalaCards based summary : Tetramelic Deficiencies, Ectodermal Dysplasia, Deformed Ears, and Other Abnormalities, also known as odontotrichomelic syndrome, is related to ectodermal dysplasia and ectrodactyly, ectodermal dysplasia, and cleft lip/palate syndrome 1. An important gene associated with Tetramelic Deficiencies, Ectodermal Dysplasia, Deformed Ears, and Other Abnormalities is ANTXR1 (ANTXR Cell Adhesion Molecule 1). Affiliated tissues include bone, skin and thyroid, and related phenotypes are intellectual disability and eeg abnormality
