Bpifa3, with no common aliases mentioned in the provided references, has been associated with certain biological processes.

In the context of otitis media susceptibility in childhood, the BPIFA gene cluster on chromosome 20q11.21, where Bpifa3 is located, was identified as a top hit in a gene-based analysis in VEGAS (P(Gene) = 2 × 10(-5)) [2]. Also, in skin ageing, it was found to have an odds ratio of 1.859 (95% confidence interval [1.567, 2.151]), indicating its potential role in the genetic determinants of skin ageing [1].

Although no KO/CKO mouse models' findings are presented in the references, the gene-based analysis in the otitis media study and the association in the skin ageing study suggest its significance in these disease-related biological processes. In otitis media, the association with the BPIFA gene cluster including Bpifa3 may imply its role in the body's response to middle ear inflammation. In skin ageing, the identified association with Bpifa3 points to its potential role in the complex genetic mechanisms underlying skin ageing phenotypes.

In conclusion, Bpifa3 shows promise as a gene involved in multiple disease-related biological processes, particularly in otitis media susceptibility and skin ageing. While direct evidence from KO/CKO mouse models is lacking, the current findings from the cited studies provide initial insights into its potential functions in these areas, which could be further explored in future functional studies.
