What it is
A rare, genetic, syndromic intellectual disability disorder characterized by mild to moderate intellectual disability, facial dysmorphism (including a long face, deep-set eyes, narrow-based, broad nose with nostril colobomata, mandibular prognathism), hypergonadotrophic hypogonadism, eunuchoid habitus, diabetes mellitus type 1, and epilepsy. There have been no further descriptions in the literature since 1990.

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.
