As shown in the Manhattan plot in previous question, the authors
have identified a single best candidate gene for most loci
identified in their study, but identified two candidate genes for
the locus on chromosome 3: SCN5A and SCN10A. These are
related genes that both encode cardiac sodium channels. The
regional association plot for this locus is shown above, with gene
models in this region shown below the plot. Based on the
information shown here, why did the authors nominate SCN5A
and SCN10A as candidate genes, but not SCN11A, another
cardiac sodium channel gene adjacent to SCN10A? Limit your
answer to 1-2 sentences.
Expert Solution
Step 1: Introduction.
Answer :- In the 2019 GWAS study focused on identifying loci impacting the risk of prolonged QRS duration in Hispanic/Latino individuals, the authors identified multiple candidate genes associated with different loci.
