Platelet-type bleeding disorder 11(BDPLT11)

MedGen UID:: 481750
•Concept ID:: C3280120
•: Disease or Syndrome

Synonyms:	BDPLT11; GLYCOPROTEIN VI DEFICIENCY; GP VI DEFICIENCY
SNOMED CT:	Bleeding disorder due to glycoprotein VI deficiency (765977002); Glycoprotein VI deficiency (765977002); Bleeding disorder platelet-type 11 (765977002)
Modes of inheritance:	Autosomal recessive inheritance MedGen UID: 141025 •Concept ID: C0441748 • Intellectual Product Source: Orphanet A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in individuals with two pathogenic alleles, either homozygotes (two copies of the same mutant allele) or compound heterozygotes (whereby each copy of a gene has a distinct mutant allele). Autosomal recessive inheritance (Orphanet)

Gene (location): Gene(s) directly associated with this condition or phenotype.	GP6 (19q13.42)

Definition

Platelet-type bleeding disorder-11 is an autosomal recessive mild to moderate bleeding disorder caused by defective platelet activation and aggregation in response to collagen (summary by Dumont et al., 2009). [from OMIM]

Additional description

From MedlinePlus Genetics
Glycoprotein VI deficiency is a bleeding disorder associated with a decreased ability to form blood clots. Normally, blood clots protect the body after an injury by sealing off damaged blood vessels and preventing further blood loss. Because people with glycoprotein VI deficiency cannot form blood clots normally, they have an increased risk of nosebleeds (epistaxis) and may experience abnormally heavy or prolonged bleeding following minor injury or surgery. In some affected individuals, spontaneous bleeding under the skin causes areas of discoloration (ecchymosis). Women with glycoprotein VI deficiency often have heavy or prolonged menstrual periods (menorrhagia). https://medlineplus.gov/genetics/condition/glycoprotein-vi-deficiency

Impaired ristocetin-induced platelet aggregation

MedGen UID:: 868749
•Concept ID:: C4023154
•: Pathologic Function

Abnormal response to ristocetin as manifested by reduced or lacking aggregation of platelets upon addition of ristocetin.

See: Feature record | Search on this feature

Impaired collagen-induced platelet aggregation

MedGen UID:: 870264
•Concept ID:: C4024703
•: Finding

Abnormal response to collagen or collagen-mimetics as manifested by reduced or lacking aggregation of platelets upon addition collagen or collagen-mimetics.

Ecchymosis

MedGen UID:: 8524
•Concept ID:: C0013491
•: Finding

A purpuric lesion that is larger than 1 cm in diameter.

See: Feature record | Search on this feature

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.
