In this paper, a rare case of the Rolland-Desbuquois type is presented. The case is unusual because although it was the milder form, the child died on the 10th day of life. [ncbi.nlm.nih.gov]

Abstract The dyssegmental dysplasia is a lethal form of neonatal short-limbed dwarfism in which unusual facies, short neck, narrow thorax, cleft palate, and reduced joint mobility are the characteristic commonly seen. [unboundmedicine.com]
It is characterized by irregular-sized vertebral bodies due to spinal segmental abnormalities and a distinct facial appearance, micrognathia, short neck, narrow chest, and cleft palate. [deepdyve.com]

Workup
[…] narrow the differential diagnosis of skeletal dysplasias so that appropriate confirmatory molecular tests can be selected, (2) to predict lethality; and (3) to identify the fetus with a skeletal dysplasia early enough in pregnancy so that the diagnostic workup [radiologykey.com]
(See Workup.) In affected patients with type I, problems with motor development frequently become evident during the first year of life. Usually, the characteristic dysmorphic features lead to an early diagnosis, no later than age 3 years. [img.medscape.com]
Treatment
There are two main types of clinical studies: Clinical trials determine if a new test or treatment for a disease is effective and safe by comparing groups receiving different tests/treatments. [rarediseases.info.nih.gov]

Prognosis is poor. Synonyms Dyssegmental Dwarfism Rolland-Desbuquois Type; Dyssegmental Dysplasia Rolland-Desbuquois Type; Anisospondylic Campto-Micro-Melic Dwarfism. Incidence Very rare, around 20 cases reported worldwide. [accesspediatrics.mhmedical.com]
Etiology
Although the etiology of the Rolland-Desbuquois form has not been explained, the cause of the Silverman-Handmaker type has been shown to be a lack of extracellular matrix perlecan. [cags.org.ae]
Wax JR, Cartin A, Litton C, Pinette MG, Lucas FL> ;J Clin Ultrasound. 2016-11-03 The chorionic bump: Etiologic insights from two pathologic pregnancies. [doximity.com]
Etiology: Probably autosomal recessive. Patients of Hispanic origin are well represented in the Silverman-Handmaker variety. [sonoworld.com]
(See Etiology.) The first described cases of SJS were reported in 1962 by Oscar Schwartz and Robert S. [img.medscape.com]

Pathophysiology
Pathophysiology Evidence for heparan sulphate perlecan gene 2 (HSPG2) mutations on chromosome 1p36.12, which encodes perlecan. Perlecan binds to basement membrane proteins such as collagen IV and laminin-1. [accesspediatrics.mhmedical.com]

Early treatment with surgical reduction of the tongue might often be required to prevent respiratory complications and to improve feeding. Anesthetic administration is difficult because of the airway obstruction caused by macroglossia. [jdapm.org]
