RNA Sequencing Resolves Cryptic Pathogenic Variants in Mitochondrial Disease
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Mitochondrial diseases are the most common inherited metabolic disorders, characterized by pronounced clinical and genetic heterogeneity that complicates molecular diagnosis. Although DNA‐based sequencing approaches have become standard in genetic testing, up to half of patients remain without a definitive diagnosis.

Clinical Assessment of the Nystagmus Fixation Suppression Test: An Experimental Study
Journal of International Advanced OtologyBACKGROUND: Assessment of nystagmus fixation suppression can be used as an additional diagnostic tool for patients with an acute vestibular syndrome to distinguish between a central or peripheral cause. We investigated the ability of physicians to detect

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).

Expanding the Phenotype of TUFM‐Related Combined Oxidative Phosphorylation Deficiency 4
American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Combined oxidative phosphorylation deficiency 4 (COXPD4) is a rare mitochondrial condition caused by biallelic deleterious variants in the nuclear‐encoded gene TUFM. To date, most individuals with COXPD4 have presented with encephalopathy, hypotonia, and abnormal brain imaging. Many of the reported individuals died in infancy. We aim to expand

VertiGo – a pilot project in nystagmus detection via webcam
Current Directions in Biomedical Engineering, 2020 Dizziness is one of the most common symptoms in medicine. For differentiation of peripheral or central origin of the vertigo, history and clinical examination with detection of a nystagmus is essential.

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.
