Genes affected

TASP1 (HGNC:15859): (taspase 1) This gene encodes an endopeptidase that cleaves specific substrates following aspartate residues. The encoded protein undergoes posttranslational autoproteolytic processing to generate alpha and beta subunits, which reassemble into the active alpha2-beta2 heterotetramer. It is required to cleave MLL, a protein required for the maintenance of HOX gene expression, and TFIIA, a basal transcription factor. Alternatively spliced transcript variants have been described, but their biological validity has not been determined. [provided by RefSeq, Jul 2008]

The c.589A>G (p.K197E) alteration is located in exon 8 (coding exon 7) of the TASP1 gene. This alteration results from a A to G substitution at nucleotide position 589, causing the lysine (K) at amino acid position 197 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
