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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 13, 2023The c.730A>C (p.K244Q) alteration is located in exon 9 (coding exon 9) of the PXK gene. This alteration results from a A to C substitution at nucleotide position 730, causing the lysine (K) at amino acid position 244 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
