Genes affected

PXK (HGNC:23326): (PX domain containing serine/threonine kinase like) This gene encodes a phox (PX) domain-containing protein which may be involved in synaptic transmission and the ligand-induced internalization and degradation of epidermal growth factors. Variations in this gene may be associated with susceptibility to systemic lupus erythematosus (SLE). Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]

The c.1283A>G (p.K428R) alteration is located in exon 14 (coding exon 14) of the PXK gene. This alteration results from a A to G substitution at nucleotide position 1283, causing the lysine (K) at amino acid position 428 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
