After reading Lise Barnéoud’s book “Hidden Guests” about microchimerism, I am no longer so dismissive of such claims.

AI has, shall we say, its shortcomings. A recent AI search result highlighted some of the fundamental problems with using AI for scholarly research. Among other things, it does not understand the clitoris.

Clitoral Anatomy And The Limits of AI
Everyone has an opinion about AI. It's a godsend. The spawn of Satan. The end of the world as we know it. The start of a whole new world. Just another way for the tech industry to suck blood and money out of the 99.9% to feed their bizarre dreams of immortality and eugenic perfection. A savior of humanity. The future.

Amazingly, the Cleveland Clinic will protect the clitoris of any woman under its roof. I googled “clitoral hood” while researching the history of surgeries used to cure “deviant” sexual behavior. Google’s AI informed me of this astonishing news. Warning: This may rub some people the wrong way.

A patient from my distant past recently visited a genetic counselor to discuss the implications of a result from an amnio performed when he was residing in his mother's womb. His parents came up a novel and successful way of keeping him aware of the karyotype.

Who’s Gonna’ Remember? Practical Problems of Communicating Children’s Genetic Test Results That Do Not Have Implications Until Adulthood or Reproduction
Memories are like a train/You can see them getting smaller as they pull away - from "Time" by Tom Waits. Several decades ago I counseled a couple whose amniocentesis results revealed a balanced Robertsonian translocation. The product of that pregnancy, now an adult, recently had an appointment with a genetic counselor to discuss the reproductive implications of the translocation.

Nondirectiveness in genetic counseling is a zombie concept that refuses to die. In this DNA Exchange blogpost, Jon Weil and I propose reframing nondirectiveness as a form of the psychotherapeutic concepts of safe containers and "neutral enough: counselors.

Actionability and utility are two related but poorly defined concepts in the context of genetic/genomic screening and diagnostic testing. In this blogpost I propose a framework for understanding the relationship between the two concepts.

It is easy to criticize the sins and moral shortcomings of our forebears in medical genetics and genetic counseling. But everyone is a product of their times and it is important to interpret the past and understand the present in this context. Every generation judges its predecessors.

Guest Post: They Canceled Our Anti-Eugenics Talk. The Censorship Proved Our Point.
by Ambreen Khan, Kim Zayhowski, Robert Resta, and Laura Hercher This piece is our team’s account of censorship and threats from members of the genetic counseling community. It is both testimony and a demand that our profession do better. We were twice scheduled to present a webinar on the threat of modern eugenics – only for both events to be canceled after anonymous complaints and undisclosed claims about threats and safety.

Reproductive autonomy has long been a core ethical principle of genetic counseling. But polygenic screening of embryos for non-medical traits uses the autonomy argument to justify the practice. THhs eugenic practice turns the ethical tables on us.
thednaexchange.com
Justifying Preimplantation Polygenic Embryo Screening: The Autonomy Chickens Come Home To Roost
Autonomy has been a core guiding ethical principle of genetic counselors pretty much since the profession's founding in the early 1970s. There are various definitions of autonomy but on a work-a-day basis in genetic counseling, it is usually conceptualized as the right of patients to make decisions about genetic testing that are educated and without undue external influence or pressure. It relies heavily on information-based consent.

My DNA Contains Multitudes. So Does Yours.
The genetic variation within our bodies is often neglected in discussions of DNA. But each of us contains a fantastical number of genomes that keep shape-shifting throughout our lives. We should celebrate our intra-person genetic variability. Call it IPGV, since using an acronym seems to give scientific street cred to a concept or phenomenon.

Why SRY? World Athletics Decides Who Is Female
World Athletics recently released new criteria for determining who can compete as a female in World Athletics sanctioned events. The criteria are straightforward - to compete as a female you must test negative for the SRY gene. This post critiques that criterion in light of the complexity of the development of primary and secondary sexual traits.

A recent ad campaign featuring Sydney Sweeney touting a pair of jeans has raised criticisms of eugenic overtones. Actually it's part of a long historical tradition of ads that utilize eugenic tropes to sell products.

Using Genes to Sell Eujeanics?
The controversy-du-jour in the mediaverse this past week centers on an advertising campaign for a pair of jeans by an apparel company, starring uber-celebrity Sydney Sweeney, that has raised the eugenics specter. It also capitalizes on the faded pun of jeans/genes, which gave me literary leeway to use the weak pun in the title of this posting. The controversy will likely be so short-lived that by the time this posting is up, the world will have its knickers in a twist over something else.

Last week in Part 1 I looked at the potential impact of Trump's policies on genetic counselors. Here I speculate about their impact on patients.
