m.10010T>C Mitochondrial Disease: A Case Report With Hypoparathyroidism and Review of the Literature

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Mitochondria are essential intracellular organelles that play a critical role in cellular metabolism, including the regulation of intracellular calcium signaling. Advances in genomic sequencing have facilitated the identification of rare pathogenic mitochondrial DNA (mtDNA) genetic variants in patients with unexplained endocrine disorders.

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

Genomic Contributors to Congenital Diaphragmatic Hernia: Results of Exome Sequencing in 560 Probands and Cross Reference of Findings in an Independent Cohort

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT There is a strong genetic contribution to the etiology of congenital diaphragmatic hernia (CDH). This study evaluated genetic testing results and diagnostic yield for fetuses and children with CDH. This was a retrospective cohort study of exome sequencing (ES) performed at GeneDx for fetuses and children ≤ 18 years of age with CDH compared ...

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

Long‐Term Follow Up of Two Patients With Variants in the Cluster 1031‐1159 of TRRAP Gene: Expanding the Phenotype of Developmental Delay With or Without Dysmorphic Facies and Autism

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The transformation/transcription domain‐associated protein (TRRAP) gene encodes a large multidomain protein, a member of the phosphatidylinositol 3‐kinase‐related kinase (PIKK) family. TRRAP is a component of the histone acetyltransferase (HAT) complex, and it plays an important role in gene transcription, DNA repair, and cell‐cycle regulation.

Further evidence for the involvement of EFL1 in a Shwachman-Diamond-like syndrome and expansion of the phenotypic features. [PDF]

, 2018
Recent evidence has implicated EFL1 in a phenotype overlapping Shwachman-Diamond syndrome (SDS), with the functional interplay between EFL1 and the previously known causative gene SBDS accounting for the similarity in clinical features. Relatively little

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 ...

Novel pathogenic COX20 variants causing dysarthria, ataxia, and sensory neuropathy. [PDF]

, 2019
COX20/FAM36A encodes a mitochondrial complex IV assembly factor important for COX2 activation. Only one homozygous COX20 missense mutation has been previously described in two separate consanguineous families.
