Disease or Syndrome
Synonyms: Autosomal dominant macrothrombocytopenia TUBB1-related; MACTHC1
 
Gene (location): TUBB1 (20q13.32)
 
Monarch Initiative: MONDO:0800047
OMIM®: 613112

Definition

Autosomal dominant isolated macrothrombocytopenia-1 (MACTHC1) is characterized by the finding of low platelet numbers and abnormally large platelets with irregular shapes. Affected individuals do not have increased bleeding episodes and platelet function is normal; macrothrombocytopenia is usually an incidental laboratory finding (Kunishima et al., 2009). Genetic Heterogeneity of Isolated Macrothrombocytopenia See also MACTHC2 (619840), caused by mutation in the TUBA8 gene (605742) on chromosome 22q11. [from OMIM]

Impaired platelet aggregation
MedGen UID:

•Concept ID:
C1855853
•
Finding
An impairment in the rate and degree to which platelets aggregate after the addition of an agonist that stimulates platelet clumping. Platelet aggregation is measured using aggregometer to measure the optical density of platelet-rich plasma, whereby platelet aggregation causes the plasma to become more transparent.
