ORPHA:3404Malformation syndrome
Also called Renal dysplasia-limb defects syndrome · Renal dysplasia-mesomelia-radiohumeral fusion syndrome
What it is
Ulbright-Hodes syndrome is characterised by renal dysplasia, growth retardation, phocomelia or mesomelia, radiohumeral fusion, rib abnormalities, anomalies of the external genitalia and a potter-like facies. The syndrome has been described in three infants (one pair of sibs and an unrelated case), all of whom died shortly after birth from respiratory distress resulting from pulmonary hypoplasia and oligohydramnios caused by renal dysplasia. The mode of transmission appears to be autosomal recessive.

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.
