I need to know if Single Umbilical Artery is related to x-linked icthyosis. I have three children, two boys with the disorder.  My sister is 4 1/2 months pregnant and recent ultrasound said that she only had one artery in her umbilical cord
Hits quite common to have fears if any of family member suffering with congenital disorders.I can understand your tension. Single umbilical artery is usually associated with cardiac, renal, skeletal and intestinal problems in baby. There is no studied data regarding association of ichthyosis with it. As for I know it's not related. Nothing to worry. Go for anomalous scan at 22wks.It's important to evaluate for heart, kidneys, bones & intestines. Thank youth best regardsVasundhara
