Any familial hypocalciuric hypercalcemia in which the cause of the disease is a mutation in the AP2S1 gene.

Alagille syndrome (ALGS) is a multisystem disorder with a wide spectrum of clinical variability; this variability is seen even among individuals from the same family. The major clinical manifestations of ALGS are bile duct paucity on liver biopsy, cholestasis, congenital cardiac defects (primarily involving the pulmonary arteries), butterfly vertebrae, ophthalmologic abnormalities (most commonly posterior embryotoxon), and characteristic facial features. Renal abnormalities, growth failure, behavioral differences, splenomegaly, retinal changes, and vascular abnormalities may also occur.

Autosomal recessive polycystic kidney disease – PKHD1 (ARPKD-PKHD1) is characterized by primary involvement of the kidneys and liver with mostly secondary effects seen in other organ systems. Of the three ages of initial presentation of kidney disease, the two most common are perinatal (i.e., prenatal/neonatal) and infantile (four weeks to age one year) with the classic finding of enlarged kidneys. The major difference between the perinatal and infantile presentations, which typically have similar kidney and liver findings, is the frequent occurrence of pulmonary involvement in the perinatal presentation, which is a major cause of morbidity and mortality in neonates. The less common initial presentation in childhood (after age one year) to young adulthood can be associated with predominant hepatobiliary manifestations characterized by the clinical consequences of developmental anomalies of biliary ductal plate remodeling (also known as Caroli disease). Although the short-term and long-term mortality rates of ARPKD remain significant, the survival of individuals with ARPKD has improved with modern neonatal respiratory support, kidney replacement therapy (KRT) including dialysis and kidney transplantation (KTx), and liver transplantation (LTx) or combined liver and kidney transplantation (CLKTx).

Any COACH syndrome in which the cause of the disease is a variation in the TMEM67 gene.
