Genes affected
EPPK1 (HGNC:15577): (epiplakin 1) The protein encoded by this gene belongs to the plakin family of proteins, which play a role in the organization of cytoskeletal architecture. This family member is composed of several highly homologous plakin repeats. It may function to maintain the integrity of keratin intermediate filament networks in epithelial cells. Studies of the orthologous mouse protein suggest that it accelerates keratinocyte migration during wound healing. [provided by RefSeq, Oct 2013]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2023The c.6656A>T (p.Y2219F) alteration is located in exon 1 (coding exon 1) of the EPPK1 gene. This alteration results from a A to T substitution at nucleotide position 6656, causing the tyrosine (Y) at amino acid position 2219 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
