Description

The p.Val114Met variant in MPL is classified as likely benign because it has been identified in 3.3% (2251/68026) of European chromosomes including 48 homozygotes by gnomAD (http://gnomad.broadinstitute.org, v.3.1.2). In addition, computational prediction tools predict that this variant does not impact the protein. ACMG/AMP Criteria applied: BS1, BP4.
