Summaries for Saddan

About this section
UniProtKB/Swiss-Prot:67 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.

MalaCards based summary: Saddan, also known as severe achondroplasia with developmental delay and acanthosis nigricans, is related to achondroplasia and acanthosis nigricans, and has symptoms including seizures, cognitive impairment and abnormality of the clavicle. An important gene associated with Saddan is FGFR3 (Fibroblast Growth Factor Receptor 3). Affiliated tissues include skin, brain and bone.

Genetics Home Reference:23 SADDAN (severe achondroplasia with developmental delay and acanthosis nigricans) is a rare disorder of bone growth characterized by skeletal, brain, and skin abnormalities.
