Differentiating the Clinical and Variant Spectrum of Hardikar Syndrome From Other MED12‐Related Developmental Disorders

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The rare X‐linked female‐restricted Hardikar syndrome (HDKR, OMIM # 301068) is characterized by multiple congenital anomalies including orofacial clefts, gastrointestinal, genitourinary, and cardiac anomalies, but cognitive and neurobehavioral development is rarely impaired.

Case Report With Biallelic Variants in GCNT2 Implicates Exon 1B in Congenital Cataracts

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT GCNT2‐related cataracts is a disorder characterized by bilateral congenital cataracts (CC) of various types (with or without the adult i blood phenotype) and is caused by biallelic variants in GCNT2, which has 3 major isoforms, differentiated by alternative splicing of the first exon (known as exon 1A, B, and C).

Differential alternative splicing coupled to nonsense-mediated decay of mRNA ensures dietary restriction-induced longevity

Nature Communications, 2017
Alternative splicing coupled to nonsense-mediated decay (AS-NMD) is a conserved mechanism for post-transcriptional gene regulation. Here, the authors provide evidence that AS-NMD is enhanced during dietary restriction (DR) and is required for DR-mediated

Early LQT2 Nonsense Mutation Generates N-Terminally Truncated hERG Channels with Altered Gating Properties by the Reinitiation of Translation

, 2012
Mutations in the human ether-a-go-go-related gene (hERG) result in long QT syndrome type 2 (LQT2). The hERG gene encodes a K+ channel that contributes to the repolarization of the cardiac action potential.

Biallelic Germline Inactivation of HROB Causes Primary Gonadal Insufficiency and is Potentially Associated with Colonic Polyposis Predisposition

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The Homologous Recombination Factor With OB‐Fold (HROB) plays a role in homologous recombination and DNA replication, where it enhances the MCM8‐MCM9 helicase complex activity. Recent findings link biallelic germline HROB variants to primary gonadal insufficiency (hypergonadotropic hypogonadism), a phenotype also associated with MCM8/MCM9 ...

A Upf3b-mutant mouse model with behavioral and neurogenesis defects. [PDF]

, 2018
Nonsense-mediated RNA decay (NMD) is a highly conserved and selective RNA degradation pathway that acts on RNAs terminating their reading frames in specific contexts.

Nonsense-mediated decay breaks the circle? [PDF]

Biochemical Journal, 2003
This Commentary discusses new data from the laboratory of Matthias Hentze (Schell et al., in this issue) that begins to dissect the RNA–protein and protein–protein interactions important for the process of nonsense-mediated decay (NMD). Schell and co-workers have developed a novel tool for analysis of such interactions in vivo.

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.

Nonsense‐mediated decay factor SMG7 sensitizes cells to TNFα‐induced apoptosis via CYLD tumor suppressor and the noncoding oncogene Pvt1

Molecular Oncology, 2020
Nonsense‐mediated decay (NMD) proteins are responsible for the surveillance and degradation of aberrant RNAs. Suppressor with morphogenetic effect on genitalia 7 (SMG7) is an NMD complex protein and a regulator of tumor necrosis factor (TNF)‐induced ...

Exon junction complex dependent mRNA localization is linked to centrosome organization during ciliogenesis

Nature Communications, 2021
Exon junction complexes (EJCs) that mark untranslated mRNA are involved in transport, translation and nonsense-mediated mRNA decay. Here the authors show centrosomal localization of EJCs which appears to be required for both the localization of NIN mRNA ...
