Lung agenesis-heart defect-thumb anomalies syndrome

ORPHA:1120Malformation syndrome

Also called Mardini-Nyhan syndrome

What it is

A rare genetic disease characterized by the association of unilateral complete or partial lung agenesis, complex congenital cardiac anomalies such as atrial septal defect, total anomalous pulmonary venous return, or patent ductus arteriosus, and ipsilateral or bilateral thumb abnormalities. Presence of facial dysmorphism and other malformative features has also been reported.

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.

Signs and symptoms

These ranges are how often a sign appears across everyone diagnosed, not a prediction for one person — most people have some of these and not others. Orphanet also records findings that are specifically absent in this disease; those are in the data but not listed here.

ICD-10 codes

Q87.8filed under a broader ICD-10 category — shared with 581 other rare diseases

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.
