Approximate Synonyms
  • Thanatophoric dysplasia
Clinical Information
  • A severe autosomal dominant inherited disorder caused by mutations in the fgfr3 gene. It is characterized by multiple skeletal abnormalities, including extremely short limbs. It results in the death of the neonate.
  • A severe form of neonatal dwarfism with very short limbs. All cases have died at birth or later in the neonatal period.
  • A severe skeletal dysplasia characterized chiefly by rhizomelic shortness of the limbs with skin redundancy, narrow chest with flattened vertebral bodies, a short pelvis, and disproportionately large head with frontal bossing and cloverleaf skull, prominent eyes, hypertelorism, and depressed nasal bridge. The condition is usually lethal at birth (hence the term thanatophoric meaning "death bearing," in greek) but some patients may survive into the childhood. Those who survive are severely retarded and suffer from respiratory insufficiency due to reduced chest circumference and/or lower brain stem compression caused by a small foramen magnum and a variety of central nervous system and other abnormalities. Two basic types are recognized: type i (td1) with curved femora and flat vertebral bodies. Type ii (td2) with straight femora, taller vertebral bodies, and cloverleaf skull.

Present On Admission
POA Help
"Present On Admission" is defined as present at the time the order for inpatient admission occurs — conditions that develop during an outpatient encounter, including emergency department, observation, or outpatient surgery, are considered POA.
  • Q77.1 is considered exempt from POA reporting.
