Summaries for Achondroplasia, Severe, with Developmental Delay and Acanthosis...

Genetics Home Reference : 25 SADDAN (severe achondroplasia with developmental delay and acanthosis nigricans) is a rare disorder of bone growth characterized by skeletal, brain, and skin abnormalities. All people with this condition have extremely short stature with particularly short arms and legs. Other features include unusual bowing of the leg bones; a small chest with short ribs and curved collar bones; short, broad fingers; and folds of extra skin on the arms and legs. Structural abnormalities of the brain cause seizures, profound developmental delay, and intellectual disability. Several affected individuals also have had episodes in which their breathing slows or stops for short periods (apnea). Acanthosis nigricans, a progressive skin disorder characterized by thick, dark, velvety skin, is another characteristic feature of SADDAN that develops in infancy or early childhood.

MalaCards based summary : Achondroplasia, Severe, with Developmental Delay and Acanthosis Nigricans, also known as saddan, is related to achondroplasia and hypochondroplasia, and has symptoms including seizures An important gene associated with Achondroplasia, Severe, with Developmental Delay and Acanthosis Nigricans is FGFR3 (Fibroblast Growth Factor Receptor 3), and among its related pathways/superpathways are MAPK signaling pathway and Ras signaling pathway. The drugs Simvastatin and Natriuretic Peptide, C-Type have been mentioned in the context of this disorder. Affiliated tissues include skin, brain and bone, and related phenotypes are intellectual disability, severe and aplasia/hypoplasia of the mandible

Disease Ontology : 12 A syndrome characterized by severe achondroplasia, developmental delay and acanthosis nigricans that has material basis in heterozygous mutation in the FGFR3 gene on chromosome 4p16.

NIH Rare Diseases : 52 The following summary is from Orphanet , a European reference portal for information on rare diseases and orphan drugs. Orpha Number: 85165 Definition Severe achondroplasia-developmental delay -acanthosis nigricans syndrome is characterised by the association of severe achondroplasia with developmental delay and acanthosis nigricans. It has been described in four unrelated individuals. Structural central nervous system anomalies, seizures and hearing loss were also reported, together with bowing of the clavicle, femur, tibia and fibula in some cases. The syndrome is caused by a Lys650Met substitution in the kinase domain of fibroblast growth factor receptor 3 (encoded by the FGFR3 gene ; 4p16.3). Visit the Orphanet disease page for more resources.

KEGG : 36 SADDAN (severe achondroplasia with developmental delay and acanthosis nigricans) is a rare skeletal dysplasia caused by a Lys650Met mutation in fibroblast growth factor receptor 3 (FGFR3).

UniProtKB/Swiss-Prot : 73 Achondroplasia, severe, with developmental delay and acanthosis nigricans: A severe form of achondroplasia associated with developmental delay and acanthosis nigricans. Patients manifest short-limb dwarfism, with a long, narrow trunk, short extremities, particularly in the proximal (rhizomelic) segments, a large head with frontal bossing, hypoplasia of the midface and a trident configuration of the hands. Acanthosis nigricans is a skin condition characterized by brown-pigmented, velvety verrucosities in body folds and creases.
