Overview

X-linked colobomatous microphthalmia-microcephaly-intellectual disability-short stature syndrome is a very rare genetic condition that affects multiple parts of the body, especially the eyes, brain development, and overall growth. The name describes the main features: 'colobomatous microphthalmia' means the eyes are smaller than normal and have a gap or hole in one of the eye structures (called a coloboma), 'microcephaly' means the head and brain are smaller than expected, 'intellectual disability' refers to challenges with learning and thinking, and 'short stature' means affected individuals tend to be shorter than average. This condition is sometimes referred to by its Orphanet code ORPHA:431140. Because this condition is X-linked, it is caused by a change (mutation) in a gene on the X chromosome. Males are usually more severely affected than females, since males have only one X chromosome. Females who carry the mutation may have milder features or sometimes no symptoms at all. There is currently no cure for this syndrome. Care focuses on managing each symptom — for example, supporting vision, helping with learning through special education, and monitoring growth and development. A team of specialists is usually needed to provide the best support for affected individuals and their families.

Key symptoms:

Smaller than normal eyes (microphthalmia)Gap or hole in part of the eye (coloboma), which can affect visionSmaller than normal head size (microcephaly)Intellectual disability — challenges with learning, memory, and problem-solvingShort stature — being shorter than most children of the same ageDelayed development of skills like sitting, walking, and talkingLow muscle tone (floppiness) in infancyPossible vision impairment or blindness depending on the eye involvementFacial features that may look different from typical

Inheritance
