Expanding Hereditary Spastic Paraplegias Limits: Biallelic SPAST Variants in Cerebral Palsy Mimics

open access: yesAnnals of Clinical and Translational Neurology, Volume 13, Issue 1, Page 108-121, January 2026.
ABSTRACT Objective Hereditary spastic paraplegias (HSP) are rare neurodegenerative disorders marked by spasticity and lower limb weakness. The most common type, SPG4, is usually autosomal dominant and caused by SPAST gene variants, typically presenting as pure HSP.

Case Series of Nizon‐Isidor Syndrome by Heterozygous Variants in MED12L With Further Evidence of Mitotic Instability in One Case With Diploid–Triploid Mosaicism

open access: yesAmerican Journal of Medical Genetics Part A, Volume 200, Issue 1, Page 205-214, January 2026.
ABSTRACT Nizon‐Isidor syndrome is a rare disorder caused by heterozygous variants in MED12L, with only eight documented cases in the literature. Here, we present three additional cases of this syndrome. Proband 1 was a 7‐year‐old female who presented with developmental delay, right‐leg hemihypertrophy, laryngeal cleft, esotropia, abnormal skin ...

Multiple Mitochondrial Dysfunction Syndrome Caused by IBA57 Gene Mutation: A Case Report and Literature Review

open access: yesMolecular Genetics &Genomic Medicine, Volume 14, Issue 1, January 2026.
We report a novel IBA57 variant in a pediatric case, with pathogenicity confirmed through familial segregation analysis, Sanger sequencing, 3D protein modeling, and evolutionary conservation studies. Mitochondrial complex activity assays demonstrated functional impairment. A comprehensive review of literature further elucidates the genotypic‐phenotypic

Combined Cryptococcal and Bacterial Meningitis in an Immunocompetent 15‐Year‐Old: A Case Report

open access: yesCase Reports in Infectious Diseases, Volume 2026, Issue 1, 2026.
Introduction Cryptococcal meningitis is a serious fungal infection of the meninges, typically seen in immunosuppressed patients. The occurrence of cryptococcal meningitis in immunocompetent individuals is very rare. Coinfection with bacterial meningitis is even more unusual. Primary Diagnoses, Interventions, and Outcomes We report the case of a 15‐year‐

Artificial Intelligence Software Changes Rare Disease Testing Strategy in Real Time: An International Case Series Using Face2Gene

open access: yesAmerican Journal of Medical Genetics Part A, Volume 197, Issue 11, November 2025.
ABSTRACT Genetic disorders commonly share features such as developmental delays, cognitive impairment, and behavioral challenges, yet many conditions also present unique dysmorphic features that distinguish them. Performing a thorough medical and family history and a detailed physical exam with attention to dysmorphic features is often the first step ...

Severe Neurological Presentation in Siblings With COQ5‐Related Primary Coenzyme Q10 Deficiency: Expanding Clinical and Molecular Spectrum

open access: yesJIMD Reports, Volume 66, Issue 6, November 2025.
ABSTRACT Coenzyme Q10 (CoQ10) is a coenzyme and antioxidant involved in multiple bioenergetic and biosynthetic processes, particularly within mitochondria. The biosynthesis of CoQ10 is a tightly regulated process that involves multiple enzymes, including the methyltransferase COQ5.

Infantile Cerebellar‐Retinal Degeneration Associated With Novel ACO2 Variants: Clinical Features and Insights From a Drosophila Model

open access: yesClinical Genetics, Volume 108, Issue 3, Page 266-278, September 2025.
Our Translational Loop integrates patient genetic data with Drosophila models to study disease mechanisms. We identified ACO2 variants in a patient linked to ICRD and show that our animal model mirrors key aspects of the disease. These insights help pinpoint therapeutic targets, advancing research toward treatments for rare genetic disorders.
