Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 3P and 2B. PP3_ModeratePP5BS1_SupportingBS2_Supporting

The NM_000130.5(F5):c.1001G>C(p.Arg334Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000125 in 1,614,068 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R334G) has been classified as Likely benign.

Genes affected

F5 (HGNC:3542): (coagulation factor V) This gene encodes an essential cofactor of the blood coagulation cascade. This factor circulates in plasma, and is converted to the active form by the release of the activation peptide by thrombin during coagulation. This generates a heavy chain and a light chain which are held together by calcium ions. The activated protein is a cofactor that participates with activated coagulation factor X to activate prothrombin to thrombin. Defects in this gene result in either an autosomal recessive hemorrhagic diathesis or an autosomal dominant form of thrombophilia, which is known as activated protein C resistance.

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.928

PP5

Variant 1-169555299-C-G is Pathogenic according to our data. Variant chr1-169555299-C-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 644.

BS1

Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.00013 (190/1461852) while in subpopulation MID AF = 0.00191 (11/5768). AF 95% confidence interval is 0.00107. There are 2 homozygotes in GnomAdExome4. There are 97 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High Homozygotes in GnomAdExome4 at 2 AD,AR geneVariant has number of homozygotes lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
