COX14 Variants Are Associated With Mitochondrial Complex IV Deficiency Nuclear Type 10 (MC4DN10)

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT COX14 encodes a transmembrane protein essential for cytochrome c oxidase (COX) complex assembly. A homozygous missense variant in COX14 was reported in three siblings from a single consanguineous family with severe, fatal infantile mitochondrial complex IV deficiency nuclear type 10 (MC4DN10; MIM# 619053).

Heterozygous Variants in LRP1 Cause a Neurodevelopmental Disorder With Congenital Heart Defects

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT LRP1 encodes the low‐density lipoprotein (LDL) receptor‐related protein 1 (LRP1), a transmembrane protein involved in endocytosis and activation of multiple signaling pathways. LRP1 variants have been implicated in the pathogenesis of congenital heart defects (CHD), Alzheimer's disease, and neurodevelopmental disorders (NDD).

Neonatal Botulism: A Case Series Suggesting Varied Presentations

, 2023
Infantile botulism is an uncommon diagnosis and rarer still in the neonatal period. We describe three cases of neonatal-onset botulism that presented with symptoms typically (hypotonia, constipation, facial diplegia) or atypically seen in older infants ...

A Novel Constitutional TUBB Variant Associated With Familial Malformations of Cortical Development

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Most pathogenic tubulin variants arise de novo in sporadic patients, causing severe brain malformations and significant neurodevelopmental impairment. The resulting reproductive disadvantage typically prevents these mutations from being transmitted to offspring.

L‐Cysteine and N‐Acetylcysteine Supplementation Improves Clinical Outcome in a Patient With COXPD10

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT MTO1 is a nuclear gene that encodes a mitochondrial protein essential for modifying mitochondrial transfer RNAs (tRNAs) and stabilizing codon‐anticodon interactions to ensure accurate and efficient mitochondrial protein synthesis and oxidative phosphorylation.

Expanding the Phenotypic Spectrum of TXNDC15‐Related Ciliopathies to Include Joubert Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Biallelic loss‐of‐function variants in TXNDC15 are a known cause of the perinatally lethal ciliopathy Meckel syndrome (MKS). TXNDC15 encodes an endoplasmic reticulum (ER)‐resident thioredoxin‐domain protein required for ciliary transition zone integrity.
