HIGM1 is an immunoglobulin isotype switch defect characterized by elevated concentrations of serum IgM and decreased amounts of all other isotypes. Affected males present at an early age (usually within the first year of life) recurrent bacterial and opportunistic infections, including Pneumocystis carinii pneumonia and intractable diarrhea due to cryptosporidium infection. Despite substitution treatment with intravenous immunoglobulin, the overall prognosis is rather poor, with a death rate of about 10% before adolescence.<ref>PMID:7678782</ref> <ref>PMID:7679206</ref> <ref>PMID:8094231</ref> <ref>PMID:7679801</ref> <ref>PMID:7717401</ref> <ref>PMID:7532185</ref> <ref>PMID:8889581</ref> <ref>PMID:8550833</ref> <ref>PMID:9150729</ref> <ref>PMID:9746782</ref> [[https://www.uniprot.org/uniprot/TNR5_HUMAN TNR5_HUMAN]] Defects in CD40 are the cause of immunodeficiency with hyper-IgM type 3 (HIGM3) [MIM:[https://omim.org/entry/606843 606843]].
