Genetic and Phenotypic Features of the Five Known Polyaminopathies: A Critical Narrative Review

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Polyaminopathies are a recently described family of rare genetic neurodevelopmental disorders. Polyaminopathies disrupt the biosynthesis of the primary polyamines: putrescine, spermidine, and spermine. Snyder–Robinson syndrome results from hemizygous loss‐of‐function variants in the spermine synthase (SMS) gene, resulting in decreased or ...

Noonan Syndrome Spectrum Disorders Predispose to Systemic Lupus Erythematosus: Case Report and Critical Review of the Literature

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT RASopathies are clinically overlapping neurodevelopmental syndromes resulting from germline mutations in genes involved in the rat sarcoma/mitogen‐activated protein kinases (RAS/MAPK) pathway. Historically, RASopathies have been described by clinical phenotypes, such as Noonan syndrome and Neurofibromatosis type I.

KDM2B‐Related Neurodevelopmental Disorder A Case‐Series Supporting the CxxC Domain Phenotype With Emphasis on Ocular and Dermatologic Features

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The KDM2B‐related neurodevelopmental disorder is a recently identified Mendelian disorder of the epigenetic machinery associated with pathogenic variants in KDM2B. Global developmental delay, intellectual disability, congenital anomalies, and systemic manifestations characterize the disorder.

Marfan Syndrome Associated With Intellectual Disability and Behavioral Anomalies: Further Evidence for the Effect of Compound Heterozygous Variants in FBN1 on Phenotypic Severity

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Marfan syndrome (MFS) is a rare connective tissue disorder characterized by involvement of the cardiovascular, ocular, and musculoskeletal systems. Pathogenic variants in FBN1 cause most of the MFS cases; however, intellectual disability (ID) is rarely observed. A non‐consanguineous Pakistani family with four affected individuals was recruited.

Expanding the Genotype–Phenotype Correlation of Marden–Walker Syndrome due to PIEZO2 Gene Variants: A Case Report From Brazil

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Marden–Walker syndrome (MWS; OMIM 248700) is an extremely rare congenital disorder characterized by multiple joint contractures, craniofacial dysmorphism, neurological abnormalities, and multisystem involvement. Although historically diagnosed on clinical grounds, only a few cases have been molecularly confirmed.
