For instance, in a report about SLC9A3 variants in congenital secretory sodium diarrhea 8 (OMIM: 616868), chromosomal microarray analysis revealed a heterozygous, paternally inherited 1.383 Mb deletion on chromosome 5p15.33 encompassing SLC9A3 in patient 1. This evidence concerns the gene SLC9A3 and congenital sodium diarrhea.
