Health-related quality of life in 205 children with arthrogryposis multiplex congenita.

Purpose: Arthrogryposis multiplex congenita (AMC) describes a heterogeneous group of rare congenital conditions. Health-related quality of life (HRQL) may be reduced in AMC due to broadly heterogeneous physical impairments and participation limitations. This study described HRQL in children and youth with AMC, compared HRQL between child self- and parent-proxy reports, and identified factors associated with better/worse HRQL.

The potential impact of implementation of expanded carrier screening on pediatric patient diagnoses: A retrospective chart review of patients who receive care in an outpatient genetics clinic in the northeast.

The use of expanded carrier screening (ECS) to assess reproductive risk for autosomal recessive (AR) or X-linked recessive (XLR) conditions has been increasingly integrated into obstetrical care. The aim of this study was to determine what proportion of pediatric patients seen by a medical genetics practice could have had their diagnosis predicted if the parent(s) had undergone currently available ECS at the time of data collection in 2021. A retrospective chart review of patients seen for a medical genetic evaluation at a large academic institution was performed from June 1, 2017, through June 1, 2020.

PLS3 missense variants affecting the actin-binding domains cause X-linked congenital diaphragmatic hernia and body-wall defects.

Congenital diaphragmatic hernia (CDH) is a relatively common and genetically heterogeneous structural birth defect associated with high mortality and morbidity. We describe eight unrelated families with an X-linked condition characterized by diaphragm defects, variable anterior body-wall anomalies, and/or facial dysmorphism. Using linkage analysis and exome or genome sequencing, we found that missense variants in plastin 3 (PLS3), a gene encoding an actin bundling protein, co-segregate with disease in all families.

COL11A2 as a candidate gene for vertebral malformations and congenital scoliosis.

Human vertebral malformations (VMs) have an estimated incidence of 1/2000 and are associated with significant health problems including congenital scoliosis (CS) and recurrent organ system malformation syndromes such as VACTERL (vertebral anomalies; anal abnormalities; cardiac abnormalities; tracheo-esophageal fistula; renal anomalies; limb anomalies). The genetic cause for the vast majority of VMs are unknown. In a CS/VM patient cohort, three COL11A2 variants (R130W, R1407L and R1413H) were identified in two patients with cervical VM.
