I have no MCP joint in either of my thumbs, no curvature of the spine or neck, and was diagnosed with anemia and a slight heart murmur when I was born in 1960. Is it possible that I have (or had) Aase syndrome? Exhaustive research only shows that "digital abnormalities" (usually a thumb with three instead of two joints) are a symptom.

I'm now 48, and suffering from arthritis and a narrowed spinal canal.

Are these symptoms related? What should I expect?
