Our verdict is Benign. Variant got -9 ACMG points: 2P and 11B. PM2BP4_StrongBP6_ModerateBP7BS1
The NM_031471.6(FERMT3):c.930G>T(p.Val310Val) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000496 in 1,611,560 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★). Synonymous variant affecting the same amino acid position (i.e. V310V) has been classified as Likely benign.
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.

Variant 11-64219559-G-T is Benign according to our data. Variant chr11-64219559-G-T is described in ClinVar as [Likely_benign]. Clinvar id is 1084195.Status of the report is criteria_provided_single_submitter, 1 stars.
BP7
Synonymous conserved (PhyloP=0.158 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0000919 (14/152284) while in subpopulation AFR AF= 0.000313 (13/41556). AF 95% confidence interval is 0.000185. There are 0 homozygotes in gnomad4. There are 10 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
