In my father's family it is stranger than that.

Both of the living males have dyslexia. One of them has really bad dyslexia.

Three of the five living females are autistic, and specifically have hyperlexia.

The same genes are creating different neurodivergence based off of testosterone levels. Apparently this is a thing that can happen.

My aunt and one of my cousins seem to have escaped, but it's entirely possible it's just very mild.

My grandfather was probably dyslexic too, but I never found out for sure. He certainly spent his entire life working entirely with his hands and I never saw him pick up a book except a pictorial bird guide. Fine photographer, though.
