Diastrophic dysplasia (DTD) is caused by biallelic pathogenic variants in the SLC26A2 gene. We report the case of a 49-year-old female with DTD and esophageal stenosis. This broadens the phenotypic spectrum in adult patients with DTD and raises awareness of extra-skeletal manifestations that could develop in later stages of life.

UNASSIGNED: Diastrophic dysplasia (DTD) results from SCN26A2 gene mutation, with autosomal recessive inheritance and widely variable phenotype. The gene has been mapped to chromosome 5q32-q33.1.
UNASSIGNED: We present a case of a 4-year-old female with short stature, bilateral feet and knee deformity, and dysplastic facies. SCN26A2 mutations were seen in patient as well as parents. She underwent multiple orthopedic procedures involving metatarsals, gastrosoleus, and distal femur. Based on typical clinical features, DTD was suspected. Genetic studies of patient and parents provided the exact diagnosis in this case.
UNASSIGNED: Genetic diagnosis and family counseling are important caveat of management. Key features like ear abnormalities help to suspect diagnosis which requires a high index of suspicion. Associated bony and soft-tissue abnormalities of lower limb may require surgical intervention for improvement of gait, functions, and cosmesis.

Cervical kyphosis in diastrophic dysplasia (DTD) is a very dangerous deformity which may lead to compression of neural structures resulting in tetraplegia or even. Treatment of this deformity is usually surgical, but no long-term follow-up studies are presented in the literature. Authors present a case of two children with DTD who underwent anterior corpectomy due to severe cervical kyphosis. The kyphotic deformity was corrected and the normal spinal canal width was restored. The effects of the correction remained stable for respectively 6 and 10 years of the follow-up period. The unique follow-up confirms that this type of intervention leads to an effective and long lasting results. Significant cervical kyphosis in patients suffering from DTD may be treated surgically using anterior approach even in young children with a favorable and lasting results.
