Genes affected

PTP4A1 (HGNC:9634): (protein tyrosine phosphatase 4A1) This gene encodes a member of a small class of prenylated protein tyrosine phosphatases (PTPs), which contain a PTP domain and a characteristic C-terminal prenylation motif. The encoded protein is a cell signaling molecule that plays regulatory roles in a variety of cellular processes, including cell proliferation and migration. The protein may also be involved in cancer development and metastasis. This tyrosine phosphatase is a nuclear protein, but may associate with plasma membrane by means of its prenylation motif. Pseudogenes related to this gene are located on chromosomes 1, 2, 5, 7, 11 and X. [provided by RefSeq, Jun 2013]

The c.413G>A (p.R138H) alteration is located in exon 6 (coding exon 5) of the PTP4A1 gene. This alteration results from a G to A substitution at nucleotide position 413, causing the arginine (R) at amino acid position 138 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
