I have a rare medical condition that can affect 1 in 5000 to 1 in 40,000 depending on the subtype. I have been clinically diagnosed but awaiting genetic testing. There are 12 subtypes & some are autosomal recessive or dominant. I believe due to the inheritance pattern the condition I have is autosomal dominant. I believe this because my son, me, my father & his mother all have the condition. For it to fall into the autosomal recessive category it would be highly unlikely to be passed through 4 generations given that both parents would need the mutated gene. From what I have researched it appears to be autosomal dominant given that only one parent needs to have the mutated gene which would mean there is a 50/50 chance of it been passed down through generations. Could someone please confirm this?
