INTRODUCTION.
Diastrophic dysplasia in table the ABOVE is an autosomal recessive dysplasia which affects cartilage and bone development. (“Diastrophism” is a general word referring to a twisting). Diastrophic dysplasia is due to mutations in the SLC26A2 gene.o
There is evidence diastrophic dysplasia (DTD) is caused by homozygous or compound heterozygous mutation in the solute carrier-26 member-2 (SLC26A2) gene on cytogenetic location 5q32 and genomic coordinates 5:149,960,758-149,987,400 . The screenshot of the SLC26A2 gene 26,643 bp (base pairs) of DNA sequence length is shown BELOW. Nine (9) other genes besides SLC26A2 in the 5q32 cytogenetic location are listed BENEATH.
