Genes affected

PRRX2 (HGNC:21338): (paired related homeobox 2) The DNA-associated protein encoded by this gene is a member of the paired family of homeobox proteins. Expression is localized to proliferating fetal fibroblasts and the developing dermal layer, with downregulated expression in adult skin. Increases in expression of this gene during fetal but not adult wound healing suggest a possible role in mechanisms that control mammalian dermal regeneration and prevent formation of scar response to wounding. The expression patterns provide evidence consistent with a role in fetal skin development and a possible role in cellular proliferation. [provided by RefSeq, Jul 2008]

The c.191A>G (p.E64G) alteration is located in exon 1 (coding exon 1) of the PRRX2 gene. This alteration results from a A to G substitution at nucleotide position 191, causing the glutamic acid (E) at amino acid position 64 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
