Overview

Introduction

This report serves to summarize the functional impact of missense mutations in each gene as determined by Mutation Assessor[1].

Summary

High Functional Impact Missense Mutations: 8373
Medium Functional Impact Missense Mutations: 42446
Low Functional Impact Missense Mutations: 42680
Neutral Functional Impact Mutations: 29794

Results

Functional Impact by Gene

Table 1. Get Full Table A gene-level breakdown of missense mutation functional impact, ordered by MutSig rank. Includes missense mutation counts broken down by level of functional impact (high, medium, low, neutral), median functional impact score and level, and most common level(s) of functional impact (mode) per gene.

Methods & Data

Input

SKCM-TM.maf.annotated
SKCM-TM.sig_genes.txt
Mutation Assessor Scores Release 2:

hg18
hg19

A lookup is done against the relevant Mutation Assessor Scores table for each missense mutation in a given MAF file, and available functional impact score and level are appended as two new columns to generate SKCM-TM.maf.annotated. These are summarized in Table 1, sorted by MutSig rank.
