We present a fetus with bilaterally enlarged and echogenic kidneys. Prenatal testing detected compound heterozygosity for a 0.676 Mb de novo deletion and an inherited pathogenic variant in . This is the first case of autosomal recessive polycystic kidney disease (ARPKD) with a prenatally detected disease-causing deletion.

Background: The Roma population are an endogamous, genetically isolated, minority population who migrated from North-Western India to Europe from the 10 Century throughout the Byzantine period and continues to the present day. Approximately 10-12 million Romani people reside in segregated settlements in Europe, and smaller populations live in North America and China. In addition to the endogamy, they also practice consanguinity.

In southern China, α-thalassemia is the most prevalent hereditary monogenic disorder, and deletion variants are the predominant form. Conventional thalassemia diagnosis techniques are numerous, however they are all limited in their ability to detect rare deletions. Here, we discuss a family who sought genetic counseling during their fourth pregnancy after experiencing Hb Bart's hydrops fetalis in two of their previous pregnancies.

Human genetic disorders are often caused by mutations of compound heterozygosity, where each allele of the mutant gene harbors a different genetic lesion. However, studies of such mutations are hampered, due to the lack of an appropriate model. Here we describe a kinetic model of compound heterozygous variants in an obligate enzyme dimer that contains one mutation in one monomer and the other mutation in the second monomer.
