Systematic Cardiac Phenotyping of Patients With Copy Number Variants in the 15q11.2 Breakpoint 1 to Breakpoint 2 Region: A Retrospective Cohort Study From Nine Pediatric Cardiac Centers

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Microdeletions impacting 15q11.2 breakpoint (BP) 1 to BP2, adjacent to the Prader–Willi critical region, have previously described neuropsychiatric associations, with potential low penetrance presentations of congenital heart disease (CHD) also identified.

ADNP‐Related Helsmoortel–Van der Aa Syndrome: A Review of the Literature and Clinical Recommendations for Assessment and Monitoring

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT ADNP‐related Helsmoortel–Van der Aa syndrome (ADNP‐related HVDAS) is a single gene form of autism spectrum disorder (ASD) caused by pathogenic sequence variants in the activity‐dependent neuroprotective protein (ADNP) gene. In addition to ASD, ADNP‐related HVDAS is associated with a wide range of cognitive, behavioral, and physical health ...

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.

Severe Headbanging Responsive to Levodopa in a Child With FOXP1 Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT We report a 9‐year‐old female with FOXP1 syndrome due to a de novo in‐frame deletion in the FOXP1 gene. The child has a severe neurodevelopmental disorder including global developmental delay and autism spectrum disorder. At age 2, she developed severe headbanging, which was progressive and did not respond to multidisciplinary, behavioral ...

First Report of Uniparental Isodisomy of Chromosome 15 Revealing Angelman Syndrome and Microphthalmia Associated With a Novel Homozygous ALDH1A3 Variant

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Paternal isodisomy of chromosome 15 (iUPD15) is a recognized cause of Angelman syndrome (AS), accounting for approximately 2%–5% of cases. Additionally, another recognized consequence of iUPD is the unmasking of autosomal recessive disorders. However, reports of recessive disorders resulting from iUPD15 remain scarce in the literature.

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.

Systematic Review of Females With Intellectual Disability and MECP2 Duplication

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT MECP2 Duplication Syndrome (MDS) is a rare, X‐linked neurodevelopmental disorder typically affecting males. Females with MDS have been reported and are compiled here. We conducted a systematic review (PROSPERO CRD420250652426) of PubMed, EMBASE, and Google Scholar extracting individual participant data.

TTC21B: From Modifier to Causative Gene in Joubert Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Biallelic pathogenic variants in TTC21B, encoding the retrograde intraflagellar transport protein IFT139, are a known cause of renal and skeletal ciliopathies. Single heterozygous variants in this gene were found to be enriched in a cohort of patients with various ciliopathy phenotypes, including three individuals with Joubert syndrome (JS), a

UBE3A Dosage Imbalance as a Molecular Framework Linking Angelman Syndrome and Dup15q‐Associated Autism Phenotypes

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT UBE3A is a dosage‐sensitive HECT E3 ubiquitin ligase whose neuronal expression is shaped by genomic imprinting at the 15q11.2‐q13 locus. Opposite directions of UBE3A dosage imbalance contribute to distinct neurodevelopmental phenotypes: loss of maternal UBE3A underlies Angelman syndrome, whereas maternally derived 15q11.2‐q13 copy‐number gains,
