We’re excited to announce the addition of mitochondrial genome (mtDNA) constraint metrics to gnomAD, developed using data from over 56,000 individuals in gnomAD v4.1^1,2. These new metrics are designed to identify regions of the mtDNA under strong selective pressure that are thus most likely to harbor functionally important and disease-associated variants. The gnomAD browser now features mitochondrial gene constraint and regional constraint metrics.

Announcement

We have now released an extension of local ancestry-informed frequency work from the inferred Admixed American genetic ancestry group to the inferred African/African American genetic ancestry group (n=20,805) within gnomAD v4.0. This implementation of local ancestry inference (LAI) resolves the admixed ancestries of African/African American samples into their respective African and European haplotypes, leading to better-informed functional and/or clinical classifications.

Overview

Today we announce the release of a new tool, the Genetic Prevalence Estimator (GeniE, https://genie.broadinstitute.org), which uses gnomAD allele frequencies to estimate the genetic prevalence of autosomal recessive diseases. This tool was developed in partnership with the Chan Zuckerberg Initiative Rare as One Network. By removing the need for computational expertise, GeniE makes estimating the genetic prevalence of rare recessive disease more accessible to the entire genomics community.
