Modes of inheritance:
Autosomal recessive inheritance
MedGen UID:

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).
 
Gene (location): FERMT3 (11q13.1)

Definition

Leukocyte adhesion deficiency-3 (LAD3), also known as LAD1 variant (LAD1V), is an autosomal recessive disorder characterized by LAD1 (116920)-like immune deficiency and Glanzmann thrombasthenia (GT; 273800)-like bleeding problems. LAD3 results from mutations in FERMT3, or KINDLIN3, which encodes an intracellular protein that interacts with beta-integrins in hematopoietic cells. In LAD3, the adhesive functions of integrins on both leukocytes and platelets are disrupted, most likely due to defects in activation-dependent alterations of surface integrins that enable high-avidity binding to ligands on target cells, a process termed 'inside-out signaling' (Svensson et al., 2009; Zimmerman, 2009). For a discussion of genetic heterogeneity of leukocyte adhesion deficiency, see 116920. [from OMIM]

Pathologic Function
Epistaxis, or nosebleed, refers to a hemorrhage localized in the nose.
Abnormality of thrombocytes
MedGen UID:
57492
Concept ID:
C0151854
Cell or Molecular Dysfunction
An abnormality of platelets.
Abnormal bleeding
MedGen UID:
264316
Concept ID:
C1458140
Pathologic Function
An abnormal susceptibility to bleeding, often referred to as a bleeding diathesis. A bleeding diathesis may be related to vascular, platelet and coagulation defects.
Extramedullary hematopoiesis
MedGen UID:
392862
Concept ID:
C2613439
Disease or Syndrome
The process of hematopoiesis occurring outside of the bone marrow (in the liver, thymus, and spleen) in the postnatal organisms.
Osteopetrosis
MedGen UID:
18223
Concept ID:
C0029454
Finding
Abnormally increased formation of dense trabecular bone tissue. Despite the increased density of bone tissue, osteopetrotic bones tend to be more fracture-prone than normal.
Leukocytosis
MedGen UID:
9736
Concept ID:
C0023518
Disease or Syndrome
An abnormal increase in the number of leukocytes in the blood.
Sepsis
MedGen UID:
48626
Concept ID:
C0036690
Disease or Syndrome
Systemic inflammatory response to infection.
Splenomegaly
MedGen UID:
52469
Concept ID:
C0038002
Finding
Abnormal increased size of the spleen.
Abnormal lymph node morphology
MedGen UID:

Finding
A structural lymph node abnormality.
Recurrent bacterial infections
MedGen UID:
334943
Concept ID:
C1844383
Finding
Increased susceptibility to bacterial infections, as manifested by recurrent episodes of bacterial infection.
Recurrent skin infections
MedGen UID:
377848
Concept ID:
C1853193
Disease or Syndrome

Petechiae
MedGen UID:
10680
Concept ID:

Petechiae are pinpoint-sized reddish/purple spots, resembling a rash, that appear just under the skin or a mucous membrane when capillaries have ruptured and some superficial bleeding into the skin has happened. This term refers to an abnormally increased susceptibility to developing petechiae.
Subcutaneous nodule
MedGen UID:
101803
Concept ID:
C0151811
Pathologic Function
Slightly elevated lesions on or in the skin with a diameter of over 5 mm.
