Title: My son has syndactyly. If it is a dominant trait and neither my husband or myself have it, how did he get it? Post by: snelson5620 on Apr 4, 2013 My son has very minor syndactyly between two of his toes. I heard in my biology class that it is an autosomal dominant trait. If neither myself or my husband have had syndactyly, how did we pass that gene on to our son without it being visibly present? If one of us could pass it on and its a dominant trait, wouldn't it have to be in our phenotype?

I suspect that not all of the other forms of syndactyly are dominant; I admit to not looking up all of them. A more likely possibility is that your son has a developmental form -- not genetic at all. Something got squeezed at the wrong time during your pregnancy, maybe. A minor syndactyly can be corrected with surgery. Talk to your doctor. |
