Genes affected

PTPRCAP (HGNC:9667): (protein tyrosine phosphatase receptor type C associated protein) The protein encoded by this gene was identified as a transmembrane phosphoprotein specifically associated with tyrosine phosphatase PTPRC/CD45, a key regulator of T- and B-lymphocyte activation. The interaction with PTPRC may be required for the stable expression of this protein. [provided by RefSeq, Jul 2008]

CORO1B (HGNC:2253): (coronin 1B) Members of the coronin family, such as CORO1B, are WD repeat-containing actin-binding proteins that regulate cell motility (Cai et al., 2005 [PubMed 16027158]).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.14869827).

Collection Method: clinical testing

The c.386A>C (p.E129A) alteration is located in exon 2 (coding exon 2) of the PTPRCAP gene. This alteration results from a A to C substitution at nucleotide position 386, causing the glutamic acid (E) at amino acid position 129 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
