[PMID: 37209718 DOI: 10.1016/j.bbamcr.2023.119488] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Revised: 05/03/2023] [Accepted: 05/11/2023] [Indexed: 05/22/2023]
Abstract
Cerebral cavernous malformations (CCMs) are low-flow, hemorrhagic vascular lesions of the central nervous system of genetic origin, which can cause stroke-like symptoms and seizures. From the identification of CCM1, CCM2 and CCM3 as genes related to disease progression, molecular and cellular mechanisms for CCM pathogenesis have been established and the search for potential drugs to target CCM has begun. Broadly speaking, kinases are the major group signaling in CCM pathogenesis. These include the MEKK3/MEK5/ERK5 cascade, Rho/Rock signaling, CCM3/GCKIII signaling, PI3K/mTOR signaling, and others. Since the discovery of Rho/Rock in CCM pathogenesis, inhibitors for Rho signaling and subsequently other components in CCM signaling were discovered and applied in preclinical and clinical trials to ameliorate CCM progression. This review discusses the general aspects of CCM disease, kinase-mediated signaling in CCM pathogenesis and the current state of potential treatment options for CCM. It is suggested that kinase target drug development in the context of CCM might facilitate and meet the unmet requirement - a non-surgical option for CCM disease.

Abstract
Cerebrovascular malformations occur in both sporadic and inherited patterns. This paper reviews imaging and clinical features of cerebrovascular malformations with a genetic basis. Genetic diseases such as familial cerebral cavernous malformations and hereditary hemorrhagic telangiectasia often have manifestations in bone, skin, eyes, and visceral organs, which should be recognized. Genetic and molecular mechanisms underlying the inherited disorders are becoming better understood, and treatments are likely to follow. An interaction between the intestinal microbiome and formation of cerebral cavernous malformations has emerged, with possible treatment implications. Two-hit mechanisms are involved in these disorders, and additional triggering mechanisms are part of the development of malformations. Hereditary hemorrhagic telangiectasia encompasses a variety of vascular malformations, with widely varying risks, and a more recently recognized association with cortical malformations. Somatic mutations are implicated in the genesis of some sporadic malformations, which means that discoveries related to inherited disorders may aid treatment of sporadic cases. This paper summarizes the current state of knowledge of these conditions, salient features regarding mechanisms of development, and treatment prospects.

Abstract
Purpose To describe a case report of Cavernous Hemangioma of the Retina (CHR) and highlight the importance of investigating intracranial system when retinal vascular alterations are present. Observations Patient of 26 years old, with right eye fundus alteration since 7 years old, no visual complaint. In the exam, there were sacular lesions with hematic content in the macula, configurating liquid level, associated with whitish lesion suggestive of fibrosis, compatible with cavernous hemangioma; best visual accuity of 20/20 both eyes. Comparing the current retinography with the previous one, there was no significant lesion progression of the exam. By neuroimaging investigation, the Magnetic Ressonance Imaging showed multiple cavernomas. As his sister had been diagnosed with cerebral cavernous malformation 3 years before, due to termic hiposensitivity on left leg investigation, familial multiple cavernous malformation syndrome was defined. Conclusion Imaging investigation of the Central Nervous System should be considered when CHR is observed. Clinical monitoring is necessary, interventional treatment is selected only for particular cases.

Abstract
OBJECTIVE. The purpose of this study was to investigate whether MRI-typical and MRI-atypical intraosseous vascular malformations are associated with familial cerebral cavernous malformation (FCCM). MATERIALS AND METHODS. In a retrospective matched case-control study, two radiologists reviewed the spinal imaging, both CT and MRI, of 22 patients with FCCM seen between 2006 and 2017 and of age- and sex-matched control subjects for MRI-typical and MRI-atypical intraosseous vascular malformations. Quantitative analysis of lesions identified included vertebral level, size, and number of lesions. Pathologic samples from two lesions were analyzed for histologic and immunohistochemical features. Whether the presence of typical, atypical, and total intraosseous vascular malformations differed between patients and control subjects was tested. For patients with complete spinal imaging, whether intraosseous vascular malformations were associated with age, sex, brain lesion count, and spinal lesion count was also tested. RESULTS. MRI-atypical intraosseous vertebral malformations were more commonly present in patients with FCCM (p = 0.003). Sixteen lesions were found in nine patients and none in the control group. The numbers of MRI-typical intraosseous vascular malformations were similar between patients and control subjects (p = 0.480). Age was associated with typical intraosseous vascular malformations (p = 0.027), though not with atypical malformations. MRI-atypical malformations were larger (mean diameter double) than MRI-typical malformations (p = 0.023). Histologic analysis of two lesions from different patients with pathologic collapse revealed the same histologic features consistent with combined capillary-venous malformations. CONCLUSION. Vertebral capillary-venous malformations (MRI-atypical intraosseous vascular malformations) are common in patients with FCCM and may have a more aggressive clinical course than MRI-typical malformations.

Abstract
Autosomal dominant cerebral cavernous malformation (CCM) represents a genetic disorder with a high mutation detection rate given that stringent inclusion criteria are used and copy number variation analyses are part of the diagnostic workflow. Pathogenic variants in either CCM1 (KRIT1), CCM2 or CCM3 (PDCD10) can be identified in 87–98% of CCM families with at least two affected individuals. However, the interpretation of novel sequence variants in the 5′-region of CCM2 remains challenging as there are various alternatively spliced transcripts and different transcription start sites. Comprehensive genetic and clinical data of CCM2 patients with variants in cassette exons that are either skipped or included into alternative CCM2 transcripts in the splicing process can significantly facilitate clinical variant interpretation. We here report novel pathogenic CCM2 variants in exon 3 and the adjacent donor splice site, describe the natural history of CCM disease in mutation carriers and provide further evidence for the classification of the amino acids encoded by the nucleotides of this cassette exon as a critical region within CCM2. Finally, we illustrate the advantage of a combined single nucleotide and copy number variation detection approach in NGS-based CCM1/CCM2/CCM3 gene panel analyses which can significantly reduce diagnostic turnaround time.

Abstract
A 30-year-old woman presented with diplopia after resection of an intracranial cavernous malformation. Fundus examination showed an asymptomatic intraocular cavernous hemangioma of the retina. Clinicians should be aware of the potential coexistence of intraocular and intracranial cavernous malformations; the presence of both should suggest familial etiology. As with other intracranial and intraocular vascular lesions (e.g., arteriovenous malformation in Wyburn-Mason syndrome, retinal hemangioblastoma in von Hippel Lindau disease, and choroidal hemangioma in Sturge-Weber syndrome), the presence of a vascular lesion in either location should prompt evaluation for additional pathology.

Abstract
Cerebral cavernous malformation (CCM) is a capillary malformation arising in the central nervous system. CCM may occur sporadically or cluster in families with autosomal dominant transmission, incomplete penetrance, and variable expressivity. Three genes are associated with CCM KRIT1, CCM2, and PDCD10. This work is a retrospective single-center molecular study on samples from multiple Italian clinical providers. From a pool of 317 CCM index patients, we found germline variants in either of the three genes in 80 (25.2%) probands, for a total of 55 different variants. In available families, extended molecular analysis found segregation in 60 additional subjects, for a total of 140 mutated individuals. From the 55 variants, 39 occurred in KRIT1 (20 novel), 8 in CCM2 (4 novel), and 8 in PDCD10 (4 novel). Effects of the three novel KRIT1 missense variants were characterized in silico. We also investigated a novel PDCD10 deletion spanning exon 4-10, on patient's fibroblasts, which showed significant reduction of interactions between KRIT1 and CCM2 encoded proteins and impaired autophagy process. This is the largest study in Italian CCM patients and expands the known mutational spectrum of KRIT1, CCM2, and PDCD10. Our approach highlights the relevance of seeking supporting information to pathogenicity of new variants for the improvement of management of CCM.

Abstract
Evaluation for intracranial lesions in a patient with retinal cavernous hemangiomas is vital for early recognition of this heritable and potentially life-threatening disease. We report a case of a highly penetrant but variably expressed form of cerebral cavernous malformation syndrome with cerebral, cutaneous, and retinal cavernomas in a family found to harbor a nonsense mutation of the CCM1 gene.

Abstract
Purpose To determine if adrenal calcifications seen at computed tomography (CT) are associated with familial cerebral cavernous malformations (fCCMs) in carriers of the CCM1 Common Hispanic Mutation. Materials and Methods This study was approved by the institutional review board. The authors retrospectively reviewed abdominal CT scans in 38 patients with fCCM, 38 unaffected age- and sex-matched control subjects, and 13 patients with sporadic, nonfamilial cerebral cavernous malformation (CCM). The size, number, and laterality of calcifications and the morphologic characteristics of the adrenal gland were recorded. Brain lesion count was recorded from brain magnetic resonance (MR) imaging in patients with fCCM. The prevalence of adrenal calcifications in patients with fCCM was compared with that in unaffected control subjects and those with sporadic CCM by using the Fisher exact test. Additional analyses were performed to determine whether age and brain lesion count were associated with adrenal findings in patients with fCCM. Results Small focal calcifications (SFCs) (≤5 mm) were seen in one or both adrenal glands in 19 of the 38 patients with fCCM (50%), compared with 0 of the 38 unaffected control subjects (P < .001) and 0 of the 13 subjects with sporadic CCM (P = .001). Adrenal calcifications in patients with fCCM were more frequently left sided, with 17 of 19 patients having more SFCs in the left adrenal gland than the right adrenal gland and 50 of the 61 observed SFCs (82%) found in the left adrenal gland. No subjects had SFCs on the right side only. In patients with fCCM, the presence of SFCs showed a positive correlation with age (P < .001) and number of brain lesions (P < .001). Conclusion Adrenal calcifications identified on CT scans are common in patients with fCCM and may be a clinically silent manifestation of disease. © RSNA, 2017.

Abstract
Retinal cavernous hemangiomas are benign vascular anomalies that are typically unilateral and located outside of the macula. Fluorescein angiography findings include an early slow-filling, non-leaking lesion with late intermixed lobules of hyperfluorescence and hypofluoresence secondary to plasma and erythrocyte sedimentation. We present a novel case of unilateral macular cavernous hemangioma with bilateral peripheral vascular anomalies and nonperfusion. This may represent a phenotypic variation of hemangiomas that, in conjunction with recent histopathologic and genetic findings, may aid in future therapies for a disease that has been traditionally observed due to slow progression.

Abstract
Cerebral cavernous (or capillary-venous) malformations (CCM) have a prevalence of about 0.1-0.5% in the general population. Genes mutated in CCM encode proteins that modulate junction formation between vascular endothelial cells. Mutations lead to the development of abnormal vascular structures.In this article, we review the clinical features, molecular and genetic basis of the disease, and management.

Backround Retinal cavernous hemangiomas are rare vascular anomalies, and can be associated with cerebral cavernous malformations (CCM). Distinct mutations have been reported in patients who have both CCMs and retinal cavernous hemangiomas. Methods Fluorescein angiography, spectral domain optical coherence tomography, and genetic testing were performed on a patient with a retinal cavernous hemangioma and a CCM. Results Our patient was heterozygous in the KRIT1/CCM1 gene for a frameshift mutation, c.1088delC. This would be predicted to result in premature protein termination. Discussion We have identified a novel mutation in the KRIT1/CCM1 gene in a patient with both CCM and retinal cavernous hemangioma. We hypothesize that the occurrence of retinal cavernous hemangiomas and CCMs is underlaid by a common mechanism present in the KRIT1/CCM1 gene.

Abstract
Object The purpose of this study was to underline the effectiveness of molecular analysis in cerebral cavernous angioma, with special attention to the familial forms. Methods Multiplex Ligation-dependent Probe Amplification analysis integrates the consecutive sequence analysis of the 3 genes (Krit1/CCM1, MGC4607/CCM2, and PDCD10/CCM3) known to be responsible for cerebral cavernous malformation lesions. Results The Multiplex Ligation-dependent Probe Amplification analysis revealed a new mutation, a heterozygous exon 9/10 deletion of Krit1, in the proband and in all affected family members. Conclusions The identification of the molecular defect allows physicians to screen family members at risk and to identify affected individuals before the onset of clinical symptoms caused by the presence of lesions.

Abstract
BACKGROUND Familial cerebral cavernous malformations (FCCM) are vascular malformations inherited as an autosomal-dominant condition. Three genes (KRIT1/CCM1, MGC4607/CCM2, PDCD10/CCM3) have been identified so far. Extra-neurological manifestations include retinal and cutaneous vascular malformations. The cutaneous vascular malformation, which had been more specifically associated with FCCM, is hyperkeratotic cutaneous capillary venous malformation (HCCVM). OBJECTIVES To define the frequency of cutaneous vascular malformations in patients with FCCM, to precise their different phenotypes, and to study the association of each cutaneous vascular malformation subtype with the different three mutated CCM genes. METHODS Dermatological inquiry was systematically performed in a large series of consecutive FCCM patients. Cutaneous biopsies were reviewed when available. Cutaneous vascular malformations classification was based on predominant anomalous channels, using the current International Society for the Study of Vascular Anomalies classification. Molecular screening of CCM genes was performed. Results Four hundred seventeen consecutive FCCM patients from 182 unrelated families were included. 38 patients (9%) from 25 different families had cutaneous vascular malformations. In these 38 patients, cutaneous vascular malformations were classified as follows: 13 capillary malformations (CM), 15 HCCVM, 8 venous malformations (VM) and 2 unclassified lesions. All patients (92%), but one with CM had a KRIT1/CCM1 mutation. The last patient had no detectable mutation. All of the 15 patients with HCCVM had a KRIT1/CCM1 mutation; 86.7% of cutaneous vascular malformation patients (33 of 38) had a KRIT1/CCM1 mutation. CONCLUSION Cutaneous vascular malformations are seen in 9% of FCCM patients. Three distinct major cutaneous vascular malformations phenotypes were identified: HCCVM (39%), CM (34%) and VM (21%). CCM1 is the most frequently mutated gene in cutaneous vascular malformations-FCCM patients.

Abstract
Although cerebral cavernous malformations (CCMs) are not uncommon, the concurrent finding of cavernous malformations (CMs) both in the brain and spinal cord is quite rare. Furthermore, multiple spinal cord CMs are extremely rare with only a few cases being reported thus far. Recently, we encountered a 33-year-old Korean male with both CCM and multiple spinal intramedullary CMs. The patient complained of seizure and right chest paresthesia. The lesions were located throughout the neuraxis including the cerebral hemisphere, brain stem, and cervical and thoracic spinal cords. Molecular analysis of the KRIT1 (CCM1), CCM2, and PDCD10 (CCM3) genes identified a heterozygous nonsense mutation (c.103C>T; Arg35X) in the PDCD10 gene, which was reported previously in a CCM family. The patient denied a family history, however, his daughter had an identical mutation, but was asymptomatic. Three months later, after identifying the mutation in the father and the daughter, the daughter presented with seizure. To the best of our knowledge, this is the first report of an association between a mutation in the PDCD10 gene and spinal CMs.

Abstract
Ten percent of all cavernomas are familial forms. 300 independent families have been identified in France since 1995. Clinical manifestations are more frequent in familial (50%) than in sporadic forms (5%). The symptoms are the same in both forms: epilepsy, hemorrhages, neurological focal deficits and headache, but hemorrhages are more frequent and the age of revelation is younger, before 30 years. It is also frequent to observe extraneural location, cutaneous and retinal. On MRI, four types of lesional aspects were described and lesions are multiple in all cases with numerous "de novo" cavernomas. The prognostic does not depend on the number of lesions, but on their topography, especially in the brain stem. Familial forms may be considered not only as a neurological but as a systemic disease for which global management with a genetic counseling should be considered. Gene therapy is not today available, but perhaps in the future.

Abstract
Cerebral cavernous malformations (CCM) are vascular malformations that can occur as a sporadic or a familial autosomal dominant disorder. Clinical and cerebral MRI data on large series of patients with a genetic form of the disease are now available. In addition, three CCM genes have been identified: CCM1/KRIT1, CCM2/MGC4607, and CCM3/PDCD10. These recent developments in clinical and molecular genetics have given us useful information about clinical care and genetic counselling and have broadened our understanding of the mechanisms of this disorder.
