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.146C>T (p.T49M) alteration is located in exon 1 (coding exon 1) of the PTPDC1 gene. This alteration results from a C to T substitution at nucleotide position 146, causing the threonine (T) at amino acid position 49 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
