SCGN
Overview
SCGN (Secretagogin) is a calcium-binding protein validated as an IHC protein marker for the MG2 molecular group of meningiomas in an integrative molecular classification.
Alterations observed in the corpus
- SCGN protein expression was validated by IHC as a discriminative marker for the MG2 (NF2-wildtype, TRAF7/AKT1/KLF4/SMO-driven) molecular group of meningiomas; the four-marker IHC panel (S100B, SCGN, ACADL, MCM2) was proposed to enable molecular group assignment in conventional neuropathology laboratories PMID:34433969.
Cancer types (linked)
- MNG — IHC marker for MG2 molecular group in the integrative meningioma classification PMID:34433969.
Co-occurrence and mutual exclusivity
- SCGN marks MG2 meningiomas, which are NF2-wildtype and harbor point mutations in TRAF7, AKT1, KLF4, or SMO PMID:34433969.
Therapeutic relevance
- MG2 tumors (benign NF2-wildtype) may be amenable to targeted therapies directed at TRAF7/AKT1/KLF4/SMO pathways; SCGN IHC could facilitate patient selection PMID:34433969.
Open questions
- Independent validation of the IHC panel in external meningioma cohorts is required PMID:34433969.
