Genes affected

FOXN1 (HGNC:12765): (forkhead box N1) Mutations in the winged-helix transcription factor gene at the nude locus in mice and rats produce the pleiotropic phenotype of hairlessness and athymia, resulting in a severely compromised immune system. This gene is orthologous to the mouse and rat genes and encodes a similar DNA-binding transcription factor that is thought to regulate keratin gene expression. A mutation in this gene has been correlated with T-cell immunodeficiency, the skin disorder congenital alopecia, and nail dystrophy. Alternative splicing in the 5' UTR of this gene has been observed.

RSKR (HGNC:26314): (ribosomal protein S6 kinase related) Predicted to enable protein kinase activity. Predicted to be involved in protein phosphorylation. [provided by Alliance of Genome Resources, Apr 2022]
