Definition

Platelet-type bleeding disorder-25 (BDPLT25) is an autosomal dominant condition characterized by increased susceptibility to bleeding episodes due to decreased or dysfunctional platelets. Some individuals have decreased numbers of enlarged platelets or macrothrombocytopenia, whereas others have normal numbers of enlarged platelets. Platelet morphologic and functional defects are variable (Pleines et al., 2017; Stapley et al., 2022; Marin-Quilez et al., 2022). For a discussion of genetic heterogeneity of BDPLT, see 231200. [from OMIM]

Bruising susceptibility
MedGen UID:
140849
•Concept ID:
C0423798
•
Finding
An ecchymosis (bruise) refers to the skin discoloration caused by the escape of blood into the tissues from ruptured blood vessels. This term refers to an abnormally increased susceptibility to bruising. The corresponding phenotypic abnormality is generally elicited on medical history as a report of frequent ecchymoses or bruising without adequate trauma.
