Phenotype Expansion of Malan Syndrome: New Cases and a Review of the Literature

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Malan syndrome is an ultra‐rare overgrowth syndrome caused by pathogenic variants or deletions in nuclear factor one X (NFIX) located at 19p13.2. Here, we report a comprehensive literature review and phenotyping of known patients with Malan syndrome and present a novel cohort of eight patients.

Targeted Anti‐IL‐1 Immunomodulatory Therapy in Pediatric Onset PPP1R13L‐Related Arrhythmogenic Cardiomyopathy

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Autosomal recessive loss‐of‐function variants in PPP1R13L cause an ultra‐rare cardiocutaneous syndrome characterized by rapidly progressive arrhythmogenic cardiomyopathy (ACM). PPP1R13L encodes iASPP, which has two potentially overlapping mechanisms driving ACM as both a regulator of NFκB‐mediated inflammation and a binding partner within the ...

Clinical, Behavioral and Neuroradiological Phenotype in an Italian Cohort of Patients With Xia Gibbs Syndrome: A Multicenter Cross‐Sectional Study and Systematic Literature Review

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Heterozygous variants in the AHDC1 gene are associated with Xia Gibbs Syndrome (XGS), a genetic disorder with a highly variable phenotype. Cognitive impairment, motor delay, language delay, neonatal hypotonia, and sleep apnea are considered “cardinal” signs of the disease.

Vascular Abnormalities in Hypermobile Ehlers–Danlos Syndrome: A Retrospective Cohort Study

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Hypermobile Ehlers–Danlos syndrome (hEDS), while generally free from severe vascular complications, may occasionally present with cardiac and vascular abnormalities that warrant specific investigation. While studies have been conducted on the prevalence of cardiac involvement, none have focused on vascular aspects. This retrospective study was

Clinical Outcomes and Patient Experiences With Celiprolol Therapy in Vascular Ehlers–Danlos Syndrome: The First Non‐European Cohort

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Vascular Ehlers–Danlos syndrome (vEDS) is a hereditary connective tissue disorder caused by heterozygous pathogenic variants in COL3A1. European studies have shown that celiprolol may reduce the risk of life‐threatening vascular events, but outcomes in non‐European populations and the therapy's psychological impact remain unclear. We conducted

Streamlining Diagnosis of Bardet–Biedl Syndrome: New Diagnostic Algorithm With Updated Criteria

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Considerable advances have been made in our understanding of Bardet–Biedl syndrome (BBS), particularly in its core clinical features and molecular genetics, warranting an update to the existing diagnostic criteria framework. Using a rigorous, evidence‐based, and consensus‐driven process, a multidisciplinary group of international experts and ...

Electrocardiographic and Skin Manifestations of Turner Syndrome: Association With Cardiovascular Disease

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Congenital heart disease (CHD) and dermatologic conditions such as lymphedema and acquired melanocytic nevi (AMN) are common in Turner Syndrome (TS). We hypothesized that abnormalities of cranial neural crest cell derivatives drive the skin and heart manifestations of TS. We conducted joint cardiac and skin examinations of volunteers at a 2023

De Novo 2.2 Mb 19q13.42–q13.43 Microdeletion Encompassing U2AF2: Support for a Haploinsufficiency Model

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT U2 small nuclear RNA auxiliary factor 2 (U2AF2) is an essential pre‐mRNA splicing factor involved in the early stages of pre‐mRNA splicing. To date, multiple individuals have been reported with predominantly heterozygous missense variants presenting intellectual disability, speech and motor delays, seizures, hypotonia, and thin or hypoplastic ...

Spectrum of Congenital Anomalies in Myhre Syndrome—Insights Into Effects Brought by Altered TGF‐β Signaling via Gain‐of‐Function Variants in SMAD4

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Myhre syndrome is a rare genetic disorder characterized by progressive multisystem involvement. Gain‐of‐function missense heterozygous variants affecting the Ile500 residue and Arg496 residue of the SMAD4 gene are implicated in this condition.

Therapy for Myhre Syndrome: Goals, Misconceptions, and Current Agents

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Myhre Syndrome (MYHRS, MIM #139210) is a rare, multisystem connective tissue disorder caused by recurrent heterozygous gain‐of‐function pathogenic variants in the SMAD4 gene, a key player in TGF‐β signaling and a regulator of extracellular matrix homeostasis.
