Living with Short fifth metacarpals-insulin resistance syndrome
A rare genetic condition with short hand bones, insulin resistance and oddly shaped red blood cells.
Understanding Short fifth metacarpals-insulin resistance syndrome
People have a shortened fifth metacarpal (the long bone behind the pinky) on one or both hands. They also have insulin resistance, meaning the body doesn't respond well to insulin. Spherocytosis means red blood cells are round instead of flat. GARD lists onset in the teen years.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Short hand bone behind the pinky
- Insulin resistance
- Round red blood cells (spherocytosis)
- Enlarged spleen

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
