Microcephaly-short stature-limb abnormalities syndrome

What it is

A rare genetic multiple congenital anomalies syndrome characterized by severe microcephaly, intrauterine growth retardation, short stature and variable limb anomalies such as radial ray defects, short limbs, absent/hypoplastic patellae, syndactyly, brachydactyly and hypoplastic carpal or metacarpal bones. Craniofacial dysmorphism is characterized by long and broad nose, microstomia and micrognathia. Intellectual disability is mild when present. Cases with extremely severe phenotype with very short limbs and poor lung development are perinatally lethal.

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.
