ELF5

The protein encoded by this gene is a member of an epithelium-specific subclass of the ETS transcription factor family. In addition to its role in regulating the later stages of terminal differentiation of keratinocytes, it appears to regulate a number of epithelium-specific genes found in tissues containing glandular epithelium such as salivary gland and prostate. It has very low affinity to DNA due to its negative regulatory domain at the amino terminus. Two alternatively spliced transcript variants encoding different isoforms have been described for this gene.

A role in breast or prostate cancer is known.{{Cite journal| vauthors = Piggin CL, Roden DL, Gallego-Ortega D, Lee HJ, Oakes SR, Ormandy CJ| title = ELF5 isoform expression is tissue-specific and significantly altered in cancer | journal = Breast Cancer Research | volume = 18 | at = 4 | date = 7 January 2016 | issue = 1 | doi = 10.1186/s13058-015-0666-0| pmid = 26738740 | pmc = 4704400 | doi-access = free }} There are preliminary reports that the C allele genetic variant of rs61882275 near chromosome location 11.13 with variable incidence in human populations{{cite web | title = dbSNP Short Genetic Variations: rs61882275| url = https://www.ncbi.nlm.nih.gov/snp/rs61882275| access-date = January 21, 2022}} is associated with severe COVID-19.{{Cite medRxiv |vauthors=Kousathanas A, et al |date=8 September 2021 |title=Whole genome sequencing identifies multiple loci for critical illness caused by COVID-19 |medrxiv=10.1101/2021.09.02.21262965}} Further investigation by others suggested the association was caused by a tissue-specific effect on ELF5 expression in lung endothelium by this allele which results in a more than 4-fold higher risk of severe COVID-19 in those with SARS-CoV2 infection.{{Cite medRxiv |vauthors=Pietzner M, et al |date=19 January 2022 |title=ELF5 is a respiratory epithelial cell-specific risk gene for severe COVID-19 |medrxiv=10.1101/2022.01.17.22269283}}
