Description : 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).;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the fermitin family (Drosophila) homolog 3 gene (FERMT3, 607901.0001);
