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.

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.

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.

Association between suspected Zika virus disease during pregnancy and giving birth to a newborn with congenital microcephaly: a matched case–control study

BMC Research Notes, 2017
Objective In early 2015, an outbreak of an acute exanthematous illness with dengue-like symptoms occurred in northeastern Brazil. By the end of the same year, an unexpected increase in the number of cases of microcephaly was observed in the region.

Microcephaly, an etiopathogenic vision

Pediatrics and Neonatology, 2021
Microcephaly is defined by an occipital-frontal head circumference (OFD) 2 standard deviations (SD) smaller than the average expected for age, gender and population. Its incidence has been reported between 1.3 and 150 cases per 100,000 births. Currently,

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.

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

American 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.

Prenatal Evaluation of RNU4‐2 Variants in Fetuses With Central Nervous System Anomalies

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Fetal central nervous system (CNS) anomalies are among the most common congenital malformations, yet the overall prenatal diagnostic yield of current genetic testing remains below 40%. Variants in RNU4‐2, a non‐coding gene encoding the U4 small nuclear RNA (snRNA), have recently been linked to a novel highly recurrent dominant ...
