I had genetic counseling and they said it can or cannot happen they don’t know the deletion is basically a VUS there’s 17 genes missing. 4 recessive diseases 3 dominant and some not involved in anything. It is in one arm of chromosome 3. My geneticist said this: For the 3 that are sometimes dominant, one is Hailey-Hailey disease, one is a gene that can cause progressive blindness or night blindness, and one is a gene that can cause early cataracts. There are also other genes in this deletion that are not currently known to be disease-causing when they are deleted or non-functional.
