What it is

X-linked colobomatous microphthalmia-microcephaly-intellectual disability-short stature syndrome is a rare syndromic microphthalmia disorder characterized by microphthalmia with coloboma (which may involve the iris, cilary body, choroid, retina and/or optic nerve), microcephaly, short stature and intellectual disability. Other eye abnormalities such as pendular nystagmus, esotropia and ptosis may also be present. Additional associated abnormalities include kyphoscoliosis, anteverted pinnae with minimal convolutions, diastema of the incisors and congenital pes varus.

Prevalence figures describe populations, not individuals, and are often estimates from a single study. Where the figure is an incidence or a birth prevalence, it says so.

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.

Reached through the ICD-10 categories this disease is filed under, so these describe the broader group rather than this disease specifically.
