Summaries for Tetraamelia Syndrome 2

UniProtKB/Swiss-Prot : 73 Tetraamelia syndrome 2: A form of tetraamelia, a rare disease characterized by rudimentary appendages or complete absence of all four limbs, and other anomalies such as craniofacial, nervous system, pulmonary, skeletal and urogenital defects. TETAMS2 patients manifest limb deformities, bilateral agenesis of the lungs, abnormalities of the pulmonary vasculature, labioscrotal fold aplasia, and dysmorphic features including bilateral cleft lip/palate, ankyloglossia, mandibular hypoplasia, and microretrognathia. TETAMS2 transmission pattern is consistent with autosomal recessive inheritance.

MalaCards based summary : Tetraamelia Syndrome 2, is also known as tetams2. An important gene associated with Tetraamelia Syndrome 2 is RSPO2 (R-Spondin 2). Affiliated tissues include lung, heart and testes, and related phenotypes are low-set ears and micropenis

OMIM : 56 Tetraamelia syndrome-2 (TETAMS2) is characterized by rudimentary appendages or complete absence of the limbs, usually symmetric, as well as bilateral agenesis of the lungs. There are abnormalities of the pulmonary vasculature and dysmorphic features, including bilateral cleft lip/palate, ankyloglossia, mandibular hypoplasia, microretrognathia, and labioscrotal fold aplasia (Szenker-Ravi et al., 2018). For a discussion of genetic heterogeneity of TETAMS, see 273395. (618021)
