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 ...

Remote Language Assessment in School‐Age Children With Phelan–McDermid Syndrome and Genotype–Phenotype Correlation

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT People with Phelan–McDermid syndrome (PMS) have reduced speech and language abilities, yet little research has profiled the communication abilities in this population. The purpose of this study was threefold: identifying the language and communication profiles of school‐aged children with PMS, identifying genetic contributions to language and ...

The 9th International RASopathies Symposium

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The RASopathies are a group of congenital disorders with overlapping clinical manifestations that are caused by pathogenic germline or early somatic variants that result in the hyperactivation of the RAS/mitogen‐activated protein kinase (MAPK) signaling pathway.

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.

35 Individuals With HUWE1‐Related Neurodevelopmental Disorder and Suggested Clinical Evaluations

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT HUWE1 (HECT, UBA, and WWE Domain Containing E3 Ubiquitin Protein Ligase1, OMIM 300697), located at Xp11.22, encodes a ubiquitin ligase that is highly conserved across species. Genetic variants in HUWE1 described in multiple independent studies cause X‐linked intellectual disability, including in the patients identified by Juberg, Marsidi, and ...

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.

Atypical Clinical Course of Griscelli Syndrome Type 2 With Primarily Neurologic Presentation and Adult‐Onset in a 46‐Year‐Old Male

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Griscelli Syndrome Type 2 (GS2) is a rare autosomal recessive disorder caused by pathogenic mutations in the RAB27A gene. Typically, it is characterized by cutaneous hypopigmentation, immunodeficiency, with or without neurological abnormalities secondary to hemophagocytic lymphohistiocytosis (HLH). Without treatment, GS2 often results in fatal

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.

Developmental and Phenotypic Outcomes in Mild Phenylalanine Hydroxylase Deficiency

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Benign hyperphenylalaninemia (bHPA) is defined as elevated phenylalanine (Phe) levels remaining ≤ 360 μmol/L (6 mg/dL) and not requiring medical intervention. Individuals with bHPA may demonstrate a rise in their Phe levels > 360 μmol/L, effectively developing a mild PKU phenotype requiring therapy to prevent neurocognitive complications. This
