Genes affected
PTPRT (HGNC:9682): (protein tyrosine phosphatase receptor type T) The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This PTP possesses an extracellular region, a single transmembrane region, and two tandem intracellular catalytic domains, and thus represents a receptor-type PTP. The extracellular region contains a meprin-A5 antigen-PTP (MAM) domain, Ig-like and fibronectin type III-like repeats. The protein domain structure and the expression pattern of the mouse counterpart of this PTP suggest its roles in both signal transduction and cellular adhesion in the central nervous system. Two alternatively spliced transcript variants of this gene, which encode distinct proteins, have been reported. [provided by RefSeq, Jul 2008]

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 10, 2022The c.3704G>A (p.R1235H) alteration is located in exon 27 (coding exon 27) of the PTPRT gene. This alteration results from a G to A substitution at nucleotide position 3704, causing the arginine (R) at amino acid position 1235 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
