While several gain-of-function mutations that lead to C-terminal truncations, frame shifts and point mutations in the chemokine receptor CXCR4 have been identified in WHIM syndrome patients, the functional effect of these mutations are not fully understood. Here, we report on a new WHIM syndrome mutation that results in a frame shift within the codon for Ser339

decision-making on early safety hinges on the ability to pinpoint liabilities—such as hERG inhibition or mutation testing is non-negotiable in early discovery Assay sensitivity balances speed and clinical relevance Mutation

In addition to transcriptomic analysis, mutational profiles revealed that somatic mutations in OR genes OR5D18 (mouse Olfr1155) was the most frequently mutated OR gene, and OR5AR1 (mouse Olfr1019) showed IDH wild-type-specific mutation.

Using several bioinformatics tools to evaluate the impact of mutations, we found that nsSNPs rs35106420 Overall, the comprehensive application of bioinformatics tools showed that functional mutations in the
