• Frequency: Genomes: not found (cov: 32)
• Consequence: KDF1 NM_152365.3 missense
• Clinical Significance: Pathogenic no assertion criteria provided P:1
• Conservation: PhyloP100: 6.21

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]
