Gastrointestinal Manifestations in Rubinstein‐Taybi Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Rubinstein–Taybi syndrome is a rare genetic condition associated with a wide range of physical, cognitive, and developmental impairments, yet its gastrointestinal manifestations remain poorly characterized. Case reports and small series suggest a high prevalence of gastroesophageal reflux, constipation, dysphagia, and nutritional compromise ...

Glomerular Basement Membrane Protein Expression and the Diagnosis and Prognosis of Autosomal Dominant Alport Syndrome

Kidney Medicine, 2019
Alport syndrome is a hereditary glomerular nephritis associated with hearing loss and eye abnormalities and is classified as X-linked Alport syndrome, autosomal recessive Alport syndrome, and autosomal dominant Alport syndrome.

Optimizing Diagnostic Accuracy of Clinical Red Flags in RASopathies

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT RASopathies are a group of genetic disorders caused by pathogenic variants in the RAS‐mitogen‐activated protein kinase (RAS–MAPK) signaling pathway, often presenting with congenital heart defects, craniofacial dysmorphisms, and developmental delays. To assess the diagnostic yield of genetic testing in patients with suspected RASopathies and to

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).

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 ...

Evaluation of autosomal dominant retinal dystrophy genes in an unaffected cohort suggests rare or private missense variants may often be benign. [PDF]

, 2013
BackgroundMany genes have been reported as harboring autosomal dominant mutations causing retinal dystrophy. As newly available gene panel sequencing and whole exome sequencing will open these genes up to greater scrutiny, we assess the rate of rare ...

Complex Genetic Architecture in RASopathies: Constitutional PTPN11 and Mosaic RIT1 Pathogenic Variants Underlying Severe Noonan Syndrome With Adult‐Onset Acute Myeloid Leukemia

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Noonan syndrome (NS) is a genetically heterogeneous disorder characterized by a broad spectrum of clinical features resulting from dysregulation of the RAS/MAPK pathway. Although complex genotypes are increasingly recognized in NS, cases harboring two distinct pathogenic variants in different NS genes remain extremely rare.

Genotype-Phenotype Correlations in Autosomal Dominant Osteogenesis Imperfecta

Journal of Osteoporosis, 2011
Osteogenesis imperfecta, discussed in Baldridge et al. 2008 is an inherited bone fragility disorder with a wide range of clinical severity that in the majority of cases is caused by mutations in COL1A1 or COL1A2, the genes that encode the two collagen ...

De Novo Complex Genomic Rearrangement Spanning 2q31.1 in a Proband With Congenital Malformations: Genotype–Phenotype Correlation and Development of a CGR Detection Pipeline

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The 2q31 region is commonly associated with pathogenic alleles of the HOXD cluster leading to various clinical phenotypes related to skeletal development. We present a proband with tetralogy of Fallot and multiple congenital anomalies. Genomic variant screening including an in‐house CGR detection pipeline pairing genome sequencing (GS ...
