Assessing Pubertal Timing, Duration, and Related Characteristics in ASXL‐Related Disorders: A Cross‐Sectional Caregiver Survey Analysis

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Limited studies have been conducted on pubertal development in populations with pre‐existing medical conditions. More than 20‐fold increased risk of early puberty has been reported in neurodevelopmental disorders; however, this is a heterogeneous group.

The fourspine stickleback (Apeltes quadracus) has an XY sex chromosome system with polymorphic inversions on both X and Y chromosomes.

open access: yesPLoS Genetics
Teleost fish are well-known for possessing a diversity of sex chromosomes and for undergoing frequent turnovers of these sex chromosomes. However, previous studies have mainly focused on variation between species, while comparatively little attention has

The genome of Litomosoides sigmodontis illuminates the origins of Y chromosomes in filarial nematodes.

open access: yesPLoS Genetics
Heteromorphic sex chromosomes are usually thought to have originated from a pair of autosomes that acquired a sex-determining locus and subsequently stopped recombining, leading to degeneration of the sex-limited chromosome.

Case Series of Nizon‐Isidor Syndrome by Heterozygous Variants in MED12L With Further Evidence of Mitotic Instability in One Case With Diploid–Triploid Mosaicism

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Nizon‐Isidor syndrome is a rare disorder caused by heterozygous variants in MED12L, with only eight documented cases in the literature. Here, we present three additional cases of this syndrome. Proband 1 was a 7‐year‐old female who presented with developmental delay, right‐leg hemihypertrophy, laryngeal cleft, esotropia, abnormal skin ...

De Novo Variants in PPFIA2 in Individuals With Neurodevelopmental Disorders

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Liprin‐α2, encoded by PPFIA2, belongs to the family of Liprin‐α proteins which constitute major synaptic scaffolds participating in the assembly and maturation of synapses. Heterozygous de novo variants in PPFIA2 were identified by exome or genome sequencing in two unrelated individuals with a neurodevelopmental disorder.

A Collaborative Approach to Pediatric Genetic Evaluation in the Era of Genomic Medicine

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT To address the increased demand for genetic services and shortage of medical geneticists (MG), a collaborative pilot program was developed with a two‐part approach to care: (1) Initial genetic counselor (GC) appointment with exome sequencing (ES) and (2) follow‐up MG evaluation.
