SLC26A4 and diastrophic dysplasia: Pathogenic sequence alterations in SLC26 genes cause inherited diseases, including diastrophic dysplasia (phenotype MIM number 222600) and other osteochondrodysplastic syndromes (SLC26A2), secretory chloride diarrhoea (SLC26A3, phenotype MIM number 214700), Pendred syndrome (SLC26A4, phenotype MIM number 274600) and non‐syndromic deafness (SLC26A4 and A5, phenotype MIM numbers 600791 and 613865, respectively), calcium oxalate nephrolithiasis (SLC26A1 and A6, phenotype MIM number 167030), and spermatogenic failure (SLC26A8, phenotype MIM number 606766).
