Genes affected
FERMT3 (HGNC:23151): (FERM domain containing kindlin 3) Kindlins are a small family of proteins that mediate protein-protein interactions involved in integrin activation and thereby have a role in cell adhesion, migration, differentiation, and proliferation. The protein encoded by this gene has a key role in the regulation of hemostasis and thrombosis. This protein may also help maintain the membrane skeleton of erythrocytes. Mutations in this gene cause the autosomal recessive leukocyte adhesion deficiency syndrome-III (LAD-III). Alternative splicing results in multiple transcript variants encoding distinct isoforms.

Leukocyte adhesion deficiency 3 Pathogenic:2
Likely pathogenic, criteria provided, single submitterclinical testingNeuberg Centre For Genomic Medicine, NCGM-The c.1717C>T (p.Arg573Ter) stop gained variant in FERMT3 gene has been reported previously in homozygous state in a patient affected with LAD1v (Kuijpers et al., 2009). The c.1717C>T variant is novel (not in any individuals) in gnomAD Exomes and 1000 Genomes. This variant has been reported to the ClinVar database as Pathogenic. The nucleotide change c.1717C>T in FERMT3 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. Loss of function variants have been previously reported to be disease causing. However since this variant is present in the penultimate exon functional studies will be required to prove protein truncation. For these reasons, this variant has been classified as Likely Pathogenic. -
