Presentation
The patient presented with micromelic short stature, flat midface, irregular ossification of the vertebral bodies and an advanced bone age. [cags.org.ae]
Abstract : We report on three hydropic fetuses of 17, 22 and 25 gestational weeks from three distinct families presenting with Desbuquois dysplasia type 1. All fetuses showed brachymelia and characteristic dysmorphic features. [hal.archives-ouvertes.fr]
Desbuquois Dysplasia Type II: Presents all clinical features except the hand anomalies described for Type I. Kim Variant of Desbuquois Dysplasia DBQD: Described in seven patients originating from Korea and Japan. [accesspediatrics.mhmedical.com]
If, however, only one mutant copy of the gene is inherited, the individual will be a carrier of the condition, but will not be present with any symptoms. [dovemed.com]

(Etiology) Desbuquois Syndrome type 1 and Kim variant are caused by mutations in the CANT1 gene (located on chromosome 17q25.3) In some cases of Desbuquois Syndrome type 2 there are mutations in the XYLT1 gene (located on chromosome16p12), but in other [dovemed.com]
Pathophysiology
Pathophysiology Advance in molecular genetics has allowed to understand better the origin of this medical condition. However, the pathophysiology for this severe form of dwarfism and its musculoskeletal specificities remains unknown. [accesspediatrics.mhmedical.com]
Prevention
Currently, Desbuquois Syndrome may not be preventable, since it is a genetic disorder. [dovemed.com]
Therefore, due to the variety and severity of complications, identifying and reporting related mutations and using them in prenatal diagnosis is a useful diagnostic tool in the prevention of this disease and benefits children and families affected by [bmcpediatr.biomedcentral.com]
