Urinary stone disease: closing the heritability gap by challenging conventional Mendelian inheritance

Abstract

Urinary stone disease is based on gene-environment interaction with an almost 50% heritability. Despite all efforts from exome-sequencing and genome-wide association studies, the genetic factors making up for observed heritability have been incompletely characterized. The study by Sadeghi-Alavijeh etal. leverages the invaluable resources of the 100,000 Genomes Project and the UK Biobank to identify heterozygous rare variants in the phosphate transporter SLC34A3 as a significant factor of urinary stone disease, challenging the traditional concept of Mendelian inheritance.
