Tumour spectrum in -related Proteus syndrome: a systematic review of clinical reports and series.

-related Proteus syndrome is an ultra-rare mosaic overgrowth disorder with tumour predisposition. We conducted a systematic review to determine the range and characteristics of these tumours. A systematic review was conducted to identify clinical reports and clinical series of Proteus syndrome published between 1983 and 2023.

Genomic tools for health: Secondary findings as findings to be shared.

Purpose: Whether and how to disclose secondary finding (SF) information to children is ethically debated. Some argue that genetic testing of minors should be limited to preserve the child's future autonomy. Others suggest that disclosure of SFs can occur if it is in the best interests of the child.

Phenotypic Features of Cystic Lung Disease in Proteus Syndrome: A Clinical Trial.

Limited information is available regarding cystic lung disease in syndrome, a rare overgrowth disorder caused by a somatic activating variant in . To define the phenotype of cystic lung disease in syndrome. Medical records, pulmonary function tests, and chest computed tomography of 39 individuals with syndrome evaluated at a single center were retrospectively reviewed.

Development of the Clinical Gestalt Assessment: a visual clinical global impression scale for Proteus syndrome.

Background: Clinical outcome assessments are important tools for measuring the natural history of disease and efficacy of an intervention. The heterogenous phenotype and difficult to quantity features of Proteus syndrome present challenges to measuring clinical outcomes. To address these, we designed a global clinical assessment for Proteus syndrome, a rare mosaic overgrowth disorder.

Erratum: Orofacial overgrowth with peripheral nerve enlargement and perineuriomatous pseudo-onion bulb proliferations is part of the -related overgrowth spectrum.

Case report: five-year experience of AKT inhibition with miransertib (MK-7075) in an individual with Proteus syndrome.

Proteus syndrome is a rare overgrowth disorder caused by postzygotic activating variants in Individuals may develop a range of skin, bone, and soft tissue overgrowth leading to functional impairment and disfigurement. Therapy for this disorder is limited to supportive care and surgical intervention. Inhibitors of AKT, originally designed as cancer therapeutics, are a rational, targeted pharmacologic strategy to mitigate the devastating morbidity of Proteus syndrome.

A systematic literature review of disclosure practices and reported outcomes for medically actionable genomic secondary findings.

Purpose: Secondary findings (SFs) are present in 1-4% of individuals undergoing genome/exome sequencing. A review of how SFs are disclosed and what outcomes result from their receipt is urgent and timely.

Methods: We conducted a systematic literature review of SF disclosure practices and outcomes after receipt including cascade testing, family and provider communication, and health-care actions.

Cardiothoracic imaging findings of Proteus syndrome.

In this work, we sought to delineate the prevalence of cardiothoracic imaging findings of Proteus syndrome in a large cohort at our institution. Of 53 individuals with a confirmed diagnosis of Proteus syndrome at our institution from 10/2001 to 10/2019, 38 individuals (men, n = 23; average age = 24 years) underwent cardiothoracic imaging (routine chest CT, CT pulmonary angiography and/or cardiac MRI). All studies were retrospectively and independently reviewed by two fellowship-trained cardiothoracic readers.

Clinical diagnosis of presumed SOX2 gonadosomatic mosaicism.

: To describe a family with presumed gonadosomatic mosaicism diagnosed upon ophthalmic examination of the proband's mother.: The family underwent comprehensive ophthalmic and physical examination. Variant detection was performed using trio exome analysis on peripheral leukocyte DNA from blood and saliva samples.

Orofacial overgrowth with peripheral nerve enlargement and perineuriomatous pseudo-onion bulb proliferations is part of the -related overgrowth spectrum.

Individuals with orofacial asymmetry due to mucosal overgrowths, ipsilateral bone and dental aberrations with perineurial hyperplasia and/or perineuriomatous pseudo-onion bulb proliferations, comprise a recognizable clinical entity. In this article, we describe three individuals with this clinical entity and mosaic variants c.3140A>G (p.

Allelic heterogeneity of Proteus syndrome.

Proteus syndrome is a mosaic disorder that can cause progressive postnatal overgrowth of nearly any organ or tissue. To date, Proteus syndrome has been exclusively associated with the mosaic c.49G > A p.

Hypertrichotic patches as a mosaic manifestation of Proteus syndrome.

Background: Proteus syndrome is an overgrowth disorder caused by a mosaic activating AKT1 variant. Hair abnormalities in Proteus syndrome have rarely been reported, and frequencies of such findings have not been elucidated.

Objective: To define the types and frequencies of hair findings in individuals with Proteus syndrome.

A dyadic genotype-phenotype approach to diagnostic criteria for Proteus syndrome.

Phenotype-based diagnostic criteria were developed for Proteus syndrome in 1999 and updated in 2006. Subsequently, the causative mosaic gene alteration was discovered, the c.49G>A p.

Thrombosis risk factors in PIK3CA-related overgrowth spectrum and Proteus syndrome.

Increased risk of thromboembolism has been recognized in individuals with mosaic overgrowth disorders, Proteus syndrome (PS) and PIK3CA-related overgrowth spectrum (PROS), including Klippel-Trenaunay syndrome and CLOVES syndrome. PS and PROS have distinct, yet overlapping clinical findings and are caused by somatic pathogenic variants in the PI3K/AKT gene signaling pathway. PS is caused by a single somatic activating AKT1 c.

Molecular heterogeneity of the cerebriform connective tissue nevus in mosaic overgrowth syndromes.

The clinical diagnostic criteria for Proteus syndrome were defined before the discovery of the c.49G>A; p.(Glu17Lys) causal variant and used a combination of general and specific phenotypic attributes that could be combined to make a clinical diagnosis.

polyadenylation signal variants cause syndromic microphthalmia.

Background: A single variant in (c.471+2T>A), the gene encoding N-acetyltransferase 10, has been associated with Lenz microphthalmia syndrome. In this study, we aimed to identify causative variants in families with syndromic X-linked microphthalmia.

Pharmacodynamic Study of Miransertib in Individuals with Proteus Syndrome.

Proteus syndrome is a life-threatening segmental overgrowth syndrome caused by a mosaic gain-of-function AKT1 variant. There are no effective treatments for Proteus syndrome. Miransertib is an AKT1 inhibitor that, prior to this study, has been evaluated only in adult oncology trials.

Recurrent, Activating Variants in the Receptor Tyrosine Kinase DDR2 Cause Warburg-Cinotti Syndrome.

We have investigated a distinct disorder with progressive corneal neovascularization, keloid formation, chronic skin ulcers, wasting of subcutaneous tissue, flexion contractures of the fingers, and acro-osteolysis. In six affected individuals from four families, we found one of two recurrent variants in discoidin domain receptor tyrosine kinase 2 (DDR2): c.1829T>C (p.

Safety and efficacy of low-dose sirolimus in the PIK3CA-related overgrowth spectrum.

Purpose: PIK3CA-related overgrowth spectrum (PROS) encompasses a range of debilitating conditions defined by asymmetric overgrowth caused by mosaic activating PIK3CA variants. PIK3CA encodes the p110α catalytic subunit of phosphatidylinositol-3-kinase (PI3K), a critical transducer of growth factor signaling. As mTOR mediates the growth-promoting actions of PI3K, we hypothesized that the mTOR inhibitor sirolimus would slow pathological overgrowth.
