Does PMR run in families?

Posted by wandamonks @wandamonks, Jul 6, 2025

A year ago my twin sister and I were both diagnosed with PMR a week apart. Different doctors, different ailments. Had never heard of PMR before. We are female and 74 years old. Does this run in families?

I think you’ve hit the mark here. I was lucky to only get this at 72 but my son developed Tyoe 1 diabetes, also higher in Scandinavia, when he was 28. No family history of the particular disease. My daughter at 52 has just discovered by accident that she has another thing that is not quite called an autoimmune disease but is related. It only has letters iGg4. So autoimmune disease tendency is probably the better way to look at it.

@cazwell50 I had never connected PMR with Type 1 diabetes. I believe my mother and her mother had PMR (called bursitis back in the day). My brother and my nephew's son both have Type I diabetes which manifested at puberty onset. Very interesting.

I have a 74 year old twin sister. Within four days of each other we were diagnosed with PMR. Neither of us knew the other was experiencing symptoms or going to a rheumatologist. This was two years ago. She is now off prednisone and I'm getting there.

That is crazy! You are really living parallel lives. Wish the best for both of you!🙏🏻

My mother had GCA and I was told that could be why I was prone to get PMR,

At 73, I was just diagnosed with PMR yesterday. My younger sister was diagnosed with it a few years ago. Looking back, I think my older sister also had it but it was misdiagnosed. While there's nothing definitive, everything I'm reading mentions a probable genetic factor.
