Summaries for Takenouchi-Kosaki Syndrome

OMIM® : 57 Takenouchi-Kosaki syndrome is a highly heterogeneous autosomal dominant complex congenital developmental disorder affecting multiple organ systems. The core phenotype includes delayed psychomotor development with variable intellectual disability, dysmorphic facial features, and cardiac, genitourinary, and hematologic or lymphatic defects, including thrombocytopenia and lymphedema. Additional features may include abnormalities on brain imaging, skeletal anomalies, and recurrent infections. Some patients have a milder disease course reminiscent of Noonan syndrome (see, e.g., NS1, 163950) (summary by Martinelli et al., 2018). (616737) (Updated 05-Mar-2021)

MalaCards based summary : Takenouchi-Kosaki Syndrome, also known as macrothrombocytopenia and mental retardation syndrome, is related to alacrima, achalasia, and mental retardation syndrome and hypothyroidism. An important gene associated with Takenouchi-Kosaki Syndrome is CDC42 (Cell Division Cycle 42). Affiliated tissues include brain and heart, and related phenotypes are abnormal facial shape and brain imaging abnormality

UniProtKB/Swiss-Prot : 73 Takenouchi-Kosaki syndrome: A syndrome characterized by macrothrombocytopenia, lymphedema, mental retardation, developmental delay, and distinctive facial features.
