Platelet Disorders VCEP

The c.2916G>A; p.Pro972= synonymous variant has not been reported in the literature to our knowledge. It is present in a non-Finnish European control population at an allele frequency of 0.005351 and no splice impact is predicted. In summary, this variant meets criteria to be classified as benign for GT. GT-specific criteria applied: BA1, BP4, and BP7.

BA1

The overall allele frequency in gnomAD is 0.002856 with a MAF of 0.005351 (689/128,750 alleles) in the non-Finnish European population. This is above the threshold of >0.0024.

BP4

No significant splicing motif alteration detected using Human Splicing Finder and MaxEntScan.

BP7

No significant splicing motif alteration detected using Human Splicing Finder and MaxEntScan. The nucleotide is not highly conserved (PhyloP score -0.45).

PP4

This variant has been observed to be heterozygous in two individuals tested with either a "comprehensive platelet disorder panel" or "inherited thrombocytopenia panel". Both have thrombocytopenia with absent or mild bleeding phenotypes. They do not have phenotypes highly specific for GT.
