Genes affected
PTPDC1 (HGNC:30184): (protein tyrosine phosphatase domain containing 1) The protein encoded by this gene contains a characteristic motif of protein tyrosine phosphatases (PTPs). PTPs regulate activities of phosphoproteins through dephosphorylation. They are signaling molecules involved in the regulation of a wide variety of biological processes. The specific function of this protein has not yet been determined. Alternatively spliced transcript variants encoding distinct isoforms have been identified. [provided by RefSeq, Jul 2008]

The c.364C>T (p.R122C) alteration is located in exon 2 (coding exon 2) of the PTPDC1 gene. This alteration results from a C to T substitution at nucleotide position 364, causing the arginine (R) at amino acid position 122 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
