autism genetics

Post Reply New Topic

I was a family historian, a genealogist , when my kids were still at home, very young, and before the days of the internet. It was a lot more work back then to go to libraries, write and phone call, etc to get information. One thing I noticed is that in my mother's father's branch of the family there was club foot and also suicides in every generation. The young women would suicide before age 30, men would begin suicide around age 50. Every generation as far back as I could go. My daughter was born with club foot on both feet and needed intervention. My cousin was born with club feet, a couple of her kids had club feet, my sister had club feet. I found indications that there was club foot in this family line as far back as I could trace it as well. Recently I started following genetic studies of autisic people. Many genes or chromosomes are implicated, hundreds. Many tie also to genetic conditions as well. One of the genes is the same one which controls club foot. How interesting!! ! Yesterday I was thinking of all of this and remembered that another thing that seems to be passed along this family line is Nevus. My mother, brother, and sister had these big red birth marks, my same cousin who i referred to earlier also had one... now I am thinking I am going to go look up info on nevus and see if there are genes isolated and if they are also linked to autism. I should state here that I understand that there are no proven links of one between the other, just perhaps a statistical frequency that may or may not be related. So much more needs to be studied, learned, and understood.
My purpose in writing all of this is to ask if any of us happen also to have been born with either/or/and club feet or nevus. Interesting that I did not have either but definitely inherited my autism. My mother, sister, brother and cousin were/are also autistic as are many other family members and their offspring. Your input appreciated.

If a person has a heritable trait, it will usually be observed in family members. If a person has several heritable traits they will also cluster. For example a high IQ and red hair might both be heritable but not necessarily connected.

No and no.

No one in my family tree had either club feet, or nevus.

I am the only diagnosed aspie. But others on the family tree do have aspie traits. Also a number of physicists, mathmaticians, and engineers, are on the family tree. Just sayin.

No club foot in my family history, don’t know about birth marks, my NT brother had the kind of birth mark referred to as a “stork bite” when he was little but it went away, to the best of my knowledge I never had any. I’m the only one in my family I am aware of who is diagnosed as being on the autism spectrum, though the rest of my immediate family each have a few “autistic traits,” but definitely not enough to qualify for diagnosis. It seems sort of like my mom’s “autistic traits” and my dad’s combined to create me. So I’d certainly believe there could be at least some genetic factor(s) at play in my case.

Neither.

It's interesting info nonetheless. This is one of the more obnoxious things about something being a 'spectrum' and implicating hundreds of genes - there probably will be clusters of people with the same things, just many-many of them that don't intersect. It seems like it's probably still a slush fund category for all sorts of things people really don't understand, and I also sometimes wonder if it's at least in part a game-theory concoction (like for example the desire to minimize fact-oriented or logical people by labeling them with a disorder, clearly there are all sorts of sensory and motor issues that are valid concerns but can be tough to say what all is valid disability and what's simply a competitive inconvenience).

these traits are random, as far as I understand, you just inherit them randomly as well, they're not connected

Neither

I have a lot of moles on my skin and my heels have more than average external pronation or whatever it is called. I wear out my shoes on one side of my heel much more quickly.
