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.

The c.320G>A (p.R107H) alteration is located in exon 3 (coding exon 2) of the FERMT3 gene. This alteration results from a G to A substitution at nucleotide position 320, causing the arginine (R) at amino acid position 107 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

The FERMT3 c.320G>A variant is predicted to result in the amino acid substitution p.Arg107His. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.13% of alleles in individuals of South Asian descent in gnomAD. Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
