Purpose: This study aimed to assess the amount and types of clinical genetic testing denied by insurance and the rate of diagnostic and candidate genetic findings identified through research in patients who faced insurance denials.

Methods: Analysis consisted of review of insurance denials in 801 patients enrolled in a pediatric genomic research repository with either no previous genetic testing or previous negative genetic testing result identified through cross-referencing with insurance prior-authorizations in patient medical records. Patients and denials were also categorized by type of insurance coverage.

Loss of function variants in JARID2 were recently reported in 16 patients with a neurodevelopmental disorder characterized by delays, intellectual and learning disability, autism, behavioral abnormalities, and dysmorphic features. Most cases were de novo, with only one variant inherited from an affected parent. Here, we present seven additional individuals from five families with pathogenic or likely pathogenic JARID2 variants, confirming this gene-disease association and highlighting palatal abnormalities and heart defects as part of the phenotype.

Article Synopsis
  • The study focused on improving diagnosis and understanding of genetic disorders in children through the Genomic Answers for Kids program by analyzing genetic information from 960 families.
  • Researchers utilized various sequencing methods, including short-read and long-read genome sequencing, alongside machine learning to prioritize genetic variants and stored the data in a structured database for future access.
  • The results showed varying diagnostic success rates, with new diagnostic information gained from structural variants and long-read sequencing, highlighting ongoing challenges in identifying variants of unknown significance in nondiagnostic cases.

Purpose Of Review: People with cancer commonly experience persistent pain and psychological distress. Interventions are needed which address the multifactorial nature of pain and depression, yet few studies have examined the impact of mindfulness-based interventions (MBIs) for cancer-related pain and depression.

Recent Findings: MBIs for cancer-related pain and depression can be effectively delivered across a range of modalities and show promise for alleviating mood and some physical health symptoms, although not always pain.

Ambiguous genitalia in the newborn can present a diagnostic challenge in medical practice. In most cases, the causes of genitourinary anomalies are not well understood; both genetic and environmental factors are thought to play a role. In this study, we report mosaic SRY gene deletion identified by fluorescence in situ hybridization (FISH) analysis in three unrelated newborn male patients with genital anomalies.

Background: Defects in the human glycosylphosphatidylinositol anchor biosynthetic pathway are associated with inherited glycosylphosphatidylinositol (GPI)-deficiencies characterized by a broad range of clinical phenotypes including multiple congenital anomalies, dysmorphic faces, developmental delay, hypotonia, and epilepsy. Biallelic variants in PIGN, encoding phosphatidylinositol-glycan biosynthesis class N have been recently associated with multiple congenital anomalies hypotonia seizure syndrome.

Case Presentation: Our patient is a 2 year old male with hypotonia, global developmental delay, and focal epilepsy.

Background: Chromosome instability syndromes are a group of inherited conditions associated with chromosomal instability and breakage, often leading to immunodeficiency, growth retardation and increased risk of malignancy.

Case Presentation: We performed exome sequencing on a girl with a suspected chromosome instability syndrome that manifested as growth retardation, microcephaly, developmental delay, dysmorphic features, poikiloderma, immune deficiency with pancytopenia, and myelodysplasia. She was homozygous for a previously reported splice variant, c.

CHARGE syndrome is an autosomal dominant malformation syndrome associated with mutations in CHD7. The condition is typically sporadic with few familial cases reported. The diagnosis of CHARGE syndrome is based on a combination of major and minor criteria comprised of structural and functional abnormalities, most of which are part of the original CHARGE acronym, although additional anomalies have been added.
