Summaries for Yao Syndrome

OMIM : 54
Yao syndrome is an autoinflammatory disease characterized by periodic fever, dermatitis, arthritis, and swelling of the distal extremities, as well as gastrointestinal and sicca-like symptoms. The disorder is associated with specific NOD2 variants (Yao and Shen, 2017). (617321)

MalaCards based summary : Yao Syndrome, also known as yaos, is related to hepatitis and hepatitis b, and has symptoms including diarrhea, nephrolithiasis and ventricular hypertrophy. An important gene associated with Yao Syndrome is NOD2 (Nucleotide Binding Oligomerization Domain Containing 2). The drugs Dexlansoprazole and Lansoprazole have been mentioned in the context of this disorder. Affiliated tissues include bone, kidney and skin.

UniProtKB/Swiss-Prot : 71 Yao syndrome: An autoinflammatory disease characterized by periodic fever, dermatitis, polyarthritis, leg swelling, and gastrointestinal and sicca-like symptoms. YAOS is a complex disease with multifactorial inheritance.
