Variant summary

Our verdict is Benign. Variant got -15 ACMG points: 2P and 17B. PM2 BP4_Strong BP6_Very_Strong BP7 BS1

The NM_002838.5(PTPRC):c.1599G>A(p.Ser533=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000359 in 1,613,862 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Synonymous variant affecting the same amino acid position (i.e. S533S) has been classified as Likely benign.

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]

ACMG classification

Verdict is Benign. Variant got -15 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.93).
• BP6: Variant 1-198718242-G-A is Benign according to our data. Variant chr1-198718242-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 1146447.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=-4.33 with no splicing effect.
• BS1: Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.000046 (7/152100) while in subpopulation AMR AF= 0.000196 (3/15270). AF 95% confidence interval is 0.0000529. There are 0 homozygotes in gnomad4. There are 2 alleles in male gnomad4 subpopulation. This position pass quality control queck.
