Dual Aberrant Splicing Caused by an Apparently Missense CHD7 Variant, c.5273A>G (p.Asp1758Gly), in CHARGE Syndrome

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT CHARGE syndrome is a rare congenital disorder primarily attributed to heterozygous pathogenic variants of the CHD7 gene. Most pathogenic CHD7 variants are loss‐of‐function (LoF) variants, whereas the interpretation of missense variants remains challenging in the absence of functional evidence for their pathogenicity.

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

open access: yesAmerican 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.

Biallelic PAX6 Variants in an Adult With Severe Microphthalmia and Preserved Intellectual Function

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT PAX6 encodes a dosage‐sensitive transcription factor that is essential for eye development. Heterozygous PAX6 disease is well characterized, but biallelic disease is extremely rare and has been associated with anophthalmia, severe brain malformations, and perinatal lethality.

A Novel Homozygous Nonsense Variant in DCHS1 in a Brazilian Patient With Van Maldergem Syndrome Type 1: Clinical Report and Literature Review

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Van Maldergem syndrome (VMLDS) is an ultra‐rare autosomal recessive disorder characterized by craniofacial dysmorphism, intellectual disability, hypotonia, skeletal anomalies, and feeding difficulties. It is caused by biallelic variants in DCHS1 or FAT4 genes.

Recurrent Neurodevelopmental Disorder Associated With a Dominant‐Negative TOP2B H63Y Variant

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT We describe a 7 year‐old boy with severe neurodevelopmental disorder, medically‐refractory epileptic encephalopathy, hyperkinetic movement disorder, hypotonia, cerebral and cerebellar atrophy and hypomyelination who was found to have a heterozygous de novo TOP2B NM_001330700.2:c.187C>T, p.(His63Tyr) variant.

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

open access: yesAmerican 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.

Maternal Factors Modifying the Link Between Genetic Risk for Autism and Developmental Milestones

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Although common genetic liability—quantified through polygenic risk scores (PRS)—accounts for substantial variance in autism spectrum disorder (ASD) liability, how prenatal environmental exposures interact with genetic predisposition to shape developmental outcomes remains poorly understood. Using the data from Autism Genetic Resource Exchange
