Now let me compile a comprehensive answer based on all the data I've gathered. --- ## **Adenoid Cystic Carcinoma (ACC): Expected Drivers & Actionability Classification** I found dedicated ACC studies in this deployment—excellent! The largest is the **Adenoid Cystic Carcinoma Project (J Clin Invest 2019)** with 1,049 samples, plus 6 additional cohorts totaling ~1,300 samples. Let me summarize the driver landscape classified by actionability: ### **Top Somatic Mutation Drivers (by frequency)** | Gene | Altered Samples | % (of 1,298 ACC total) | Mutation Pattern | **Actionability** | |------|--------|----------|---|---| | **NOTCH1** | 250 | 19% | Truncating (nonsense, frameshift) | **CLINICAL TRIAL** (γ-secretase inhibitors) | | **KDM6A** | 154 | 12% | Loss of function | Research interest; no approved drugs | | **ARID1A** | 128 | 10% | Loss of function (SWI/SNF) | **CLINICAL TRIAL** (EZH2 inhibitors); **POTENTIAL** | | **KMT2D** | 113 | 9% | Loss of function (MLL2/KMT2D) | Research interest; epigenetic target | | **CREBBP** | 112 | 9% | Loss of function | **CLINICAL TRIAL** (histone acetyltransferase inhibitors) | | **BCOR** ↓ | **111** | **9%** | **TRUNCATING (LOF)** | ⚠️ **See detailed BCOR section below** | | **KMT2C** | 103 | 8% | Loss of function | Similar to KMT2D; research interest | | **TP53** | 80 | 6% | Mixed (missense, truncating) | Wildtype predictor of prognosis only | | **TERT** | 82 | 6% | Promoter mutations | TERT activation; limited druggability | ### **Structural Variants (Hallmark ACC Events)** | Fusion | Samples | % of cohort | **Actionability** | |--------|---------|-----------|---| | **MYB-NFIB** | 230 (~20%) | 18% | **ACTIONABLE** — Diagnostic; emerging target (BET inhibitors in development) | | **MYBL1-NFIB** | 16 | 1% | Similar to MYB-NFIB; emerging | **Note:** The MYB-NFIB fusion is the most characteristic ACC molecular event and is used diagnostically. BET inhibitors (e.g., OTX015) show activity against these translocations in preclinical/early clinical work. ### **Copy Number Alterations** | Alteration | Gene | Samples | Type | **Actionability** | |-----------|------|---------|------|---| | Amplification (2×) | PDGFRA | 40 | **ACTIONABLE** | **POTENTIAL** — PDGF inhibitors (imatinib, sunitinib); case reports | | Amplification | KIT | 34 | **ACTIONABLE** | **POTENTIAL** — KIT inhibitors (imatinib); limited data | | Deletion (-2×) | CDKN2A | 34 | Tumor suppressor loss | **POTENTIAL** — Surrogate for p16/p14 inactivation; CDK inhibitors (investigational) | --- ## **BCOR Mutations in ACC: Detailed Analysis** ### **Prevalence & Characteristics** | Metric | Value | |--------|-------| | **Total BCOR-mutant samples** | **111/1,298** (**8.5%** of ACC cohort) | | **Predominant mutation types** | **Frameshift deletions (41 samples), frameshift insertions (37 samples), nonsense mutations (20 samples)** | | **Loss-of-function mutations** | **98/111 (88%)** — truncating mutations strongly suggest tumor suppressor role | | **Missense mutations** | 16 (14%) | | **Germline vs. Somatic** | **ALL are SOMATIC** in the available data; **zero germline BCOR mutations detected** | | **Driver annotation** | **NOT annotated** as OncoKB drivers in current database | ### **BCOR Mutation Subtypes in ACC** - **Frame_Shift_Deletions:** 41 samples - **Frame_Shift_Insertions:** 37 samples - **Nonsense mutations:** 20 samples - **Missense mutations:** 16 samples - **Splice site mutations:** 2 samples ### **Pathological Context** BCOR (BCL6 corepressor) loss of function is implicated in: - **SWI/SNF-like pathway disruption** (alongside ARID1A, ARID1B mutations) - **Epigenetic remodeling** defects common across ACC (KMT2D, KDM6A, CREBBP also frequently mutated) - **Embryonic development** — BCOR loss is associated with developmental syndromes, but somatic BCOR LOF in ACC lacks established functional significance ### **Germline BCOR Considerations** **Finding:** Zero germline BCOR mutations in ACC studies. This is **important**: - **BCOR-related syndrome (oculo-facio-cardio-dental, OFCD)** is associated with germline *loss-of-function* BCOR variants, but ACC is **not** a recognized feature. - **BCOR amplifications** (not deletions) are associated with BCOR-altered CCSK (clear-cell sarcoma of kidney). - Somatic BCOR mutations in ACC are **tissue-specific**, not inherited. - **Clinical implication:** Routine germline BCOR testing for ACC is not indicated; mutations are somatic and tumor-confined. --- ## **Actionability Classification Summary** ### **Tier 1: APPROVED THERAPEUTICS / FDA-INDICATED** - **MYB-NFIB fusion:** Diagnostic hallmark; no FDA-approved inhibitors yet, but BET inhibitor development ongoing - **PDGFRA amplification / KIT amplification:** Imatinib, sunitinib (approved for GISTs, other tumors; limited ACC data) ### **Tier 2: CLINICAL TRIALS / STRONG PRECLINICAL** - **NOTCH1 mutations:** γ-secretase inhibitors (nirogacestat, etc.) in phase I/II trials for solid tumors - **ARID1A loss:** EZH2 inhibitors (e.g., tazemetostat, approved for EZH2-mutant lymphomas; ACC data limited) - **CREBBP loss:** Histone deacetylase inhibitors (vorinostat); acetyl-transferase reactivators in development ### **Tier 3: RESEARCH INTEREST / NO ACTIONABLE DRUGS YET** - **BCOR loss** ⚠️ — **Somatic BCOR mutations align with SWI/SNF disruption, but no BCOR-specific drugs exist.** Potential targets: - **EZH2 inhibitors** (cross-talk with chromatin remodeling; investigational) - **BRD4/BET inhibitors** (tested in BCOR-mutant hematologic malignancies; limited solid tumor data) - **PARP inhibitors** (synthetic lethality with SWI/SNF loss, being explored; not yet standard) - **CDK inhibitors** (indirect, via p16 inactivation if co-occurring) - **KDM6A/KMT2D loss:** Epigenetic modifiers in preclinical stages - **TP53 mutations:** Prognostic marker; MDM2 inhibitors (nutlin-3a) investigational; no approved ACC-specific TP53-targeted therapy ### **Tier 4: GERMLINE IMPLICATIONS** - **BCOR germline mutations:** Not associated with ACC; germline testing **not indicated** - **BRCA2 mutations** (67 samples, 5% ACC): Rare in ACC; if present, HRR-deficient tumors may benefit from **PARPi or platinum** in advanced disease - **TP53 germline** (Li-Fraumeni): Not routine in ACC; individualized risk assessment if strong family history --- ## **Direct Links to ACC Data** ### **1.

MD Anderson ACC Cohort (Clin Cancer Res 2015) — 102 samples, rich fusion annotations** - [**View Study**](https://www.cbioportal.org/study/summary?id=acyc_mda_2015) --- ## **Bottom Line** **In ACC, BCOR somatic mutations (9% of tumors) are loss-of-function truncations** that suggest a tumor-suppressor role in a SWI/SNF-disrupted genomic landscape, but **no established druggable BCOR target exists today**. Germline BCOR testing is not indicated for ACC. The most actionable ACC drivers are **MYB-NFIB fusions** (diagnostic, BET inhibitor interest) and **NOTCH1 mutations** (γ-secretase inhibitor trials). **ARID1A, CREBBP, and PDGFRA alterations** have emerging preclinical/clinical evidence for targeted therapy. BCOR loss is part of the chromatin remodeling signature but awaits functional validation and drug development.
