Description

The filtering allele frequency of the c.315C>T (p.Pro105=) variant in the MAP2K1 gene is 0.01% (64/66728) of European chromosomes by the Exome Aggregation Consortium, which is a high enough frequency to be classified as benign based on thresholds defined by the ClinGen RASopathy Expert Panel (BA1; PMID:29493581)
