Overview

Syndromic biliary atresia is a rare liver condition that is present from birth. In this disease, the bile ducts — the small tubes that carry bile (a digestive fluid) from the liver to the intestine — are either missing, blocked, or severely damaged. Unlike the more common isolated form of biliary atresia, the 'syndromic' type occurs alongside other birth defects in the body, such as heart problems, abnormal positioning of organs (like the spleen or intestines), or other structural differences. This combination of features suggests that the condition arises early in fetal development and may have a genetic cause. When bile cannot flow properly, it builds up inside the liver and causes serious damage over time. This leads to a condition called cholestasis (bile buildup), which causes yellowing of the skin and eyes (jaundice), pale or clay-colored stools, and dark urine in newborns. Without treatment, the liver becomes scarred (cirrhosis) and eventually fails. The main treatment is a surgery called the Kasai procedure (hepatoportoenterostomy), which tries to restore bile flow. Many children still need a liver transplant later in life. Early diagnosis and treatment are critical to giving children the best possible outcome. Research into the genetic causes of syndromic biliary atresia is ongoing, and understanding the underlying genes may open doors to better treatments in the future.

Key symptoms:

Yellowing of the skin and whites of the eyes (jaundice) in the newborn periodPale, white, or clay-colored stoolsDark yellow or brown urineSwollen or enlarged belly due to liver or spleen enlargementPoor weight gain and slow growthItchy skin from bile buildupFatigue and low energyHeart defects (present in some children)Organs on the wrong side of the body (situs inversus or polysplenia)Abnormal number or position of the spleenIntestinal malrotation (bowel in an unusual position)Easy bruising or bleeding due to poor liver functionFluid buildup in the belly (ascites) in advanced disease
