Genes affected
PTPRC (HGNC:9666): (protein tyrosine phosphatase receptor type C) 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, mitosis, and oncogenic transformation. This PTP contains an extracellular domain, a single transmembrane segment and two tandem intracytoplasmic catalytic domains, and thus is classified as a receptor type PTP. This PTP has been shown to be an essential regulator of T- and B-cell antigen receptor signaling. It functions through either direct interaction with components of the antigen receptor complexes, or by activating various Src family kinases required for the antigen receptor signaling. This PTP also suppresses JAK kinases, and thus functions as a regulator of cytokine receptor signaling. Alternatively spliced transcripts variants of this gene, which encode distinct isoforms, have been reported. [provided by RefSeq, Jun 2012]

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.47).
BP6
Variant 1-198728356-G-T is Benign according to our data. Variant chr1-198728356-G-T is described in ClinVar as Likely_benign. ClinVar VariationId is 464441.Status of the report is criteria_provided_single_submitter, 1 stars.
BP7
Synonymous conserved (PhyloP=0.999 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. GnomAdExome4 allele frequency = 0.0000178 (26/1460428) while in subpopulation AFR AF = 0.000449 (15/33436). AF 95% confidence interval is 0.000276. There are 1 homozygotes in GnomAdExome4. There are 10 alleles in the male GnomAdExome4 subpopulation. Median coverage is 30. This position passed quality control check.
