Genes affected

KDF1 (HGNC:26624): (keratinocyte differentiation factor 1) Predicted to be involved in several processes, including positive regulation of epidermal cell differentiation; regulation of epidermal cell division; and skin development. Predicted to act upstream of or within keratinocyte development and negative regulation of keratinocyte proliferation. Located in cell junction; mitotic spindle; and nucleoplasm. Implicated in ectodermal dysplasia 12. [provided by Alliance of Genome Resources, Apr 2022]
