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).

An Adult Presentation of KIF11‐Related MCLID Syndrome: Case Report and 40‐Year Follow‐Up

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Pathogenic variants in KIF11 are linked to autosomal dominant syndromes with microcephaly, chorioretinopathy, lymphedema, and intellectual disability (MCLID), though adult presentations remain underreported. We report a 42‐year‐old female presenting with a de novo single‐amino acid in‐frame deletion in the KIF11 gene (c.1294_1296del; p ...

A Rare Form of Microcephalic Primordial Dwarfism due to NSMCE2 Deficiency (Seckel Syndrome Type 10): A Report of Macular Involvement

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Biallelic variants in NSMCE2 (MMS21), which encodes the SUMO E3 ligase subunit of the SMC5/6 chromatin‐maintenance complex, have recently been implicated in microcephalic primordial dwarfism (MPD), corresponding to Seckel syndrome type 10 (OMIM #617246).

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.

Differential Diagnosis of Mucopolysaccharidoses Types I, II, III, IVA, and VI Through Analysis of Leukocytic Inclusions

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Mucopolysaccharidoses (MPS) are lysosomal storage disorders characterized by the accumulation of glycosaminoglycans (GAGs), which can lead to cytoplasmic alterations in leukocytes. The objective of this study was to characterize leukocyte inclusions in patients with different types of MPS and assess their diagnostic relevance.

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.

Mental Health Stigma in Psychiatric Genetics: Insights and Recommendations From the ISPG Member Survey on Stigma

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Little is known about how stigma is perceived within psychiatric genetics, a field increasingly central to public discussions about heredity, neurodiversity, and psychiatric risk. Understanding how stigma is perceived and experienced by psychiatric geneticists is important for guiding responsible communication and future stigma‐reduction ...

Influence of Molecular Genetic Classes on Behavior in Prader‐Willi Syndrome

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT A wide range of behavioral phenotypes has been described in PWS patients including autism spectrum disorder (ASD). The prevalence of behavioral disorders was studied in 292 participants over 3 years with genetically confirmed PWS (N = 164 females and N = 128 males) with deletion (N = 182) and mUPD (maternal uniparental disomy) (N = 99).

Genetic Variants of Na+,K+‐ATPase Associated With Neurological Disorders: A Systematic Review

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Neurological disorders encompass a wide range of severe symptoms and manifestations, many of which are associated with genetic variants that affect ionic homeostasis. Na+,K+‐ATPase, a transmembrane enzyme responsible for maintaining electrochemical gradients in cells, plays a crucial role in neuronal excitability and brain function.

Extending the ATP9A‐Related Phenotypic Spectrum: Indication of Schizophrenia Susceptibility

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT ATP9A, which belongs to the P4‐ATPase family of proteins, is involved in the efficient transport of vesicles from the Golgi apparatus to the plasma membrane, as well as the release of extracellular vesicles from human cells. In 2021, a loss‐of‐function variant of this gene was identified as being associated with a recessive neurodevelopmental ...
