Article Abstract
: Autism spectrum disorder (ASD) is a neurodevelopmental disorder that belong to genetic and epigenetic mechanism. Despite the recent advantages in next-generation sequencing (NGS) technology, ASD etiology is still unclear. : In this study, we tested a customized target genetic panel consisting of 74 genes in a cohort of 53 ASD individuals. The tested panel was designed from the SFARI database. : Among 53 patients analyzed using a targeted genetic panel, 102 rare variants were identified, with nine individuals carrying likely pathogenic or pathogenic variants considered genetically "positive." We identified six de novo variants across five genes ( 2 variants, , , , and ), including two variants of uncertain significance in p.Thr451Met and p.Glu1137Lys, one likely pathogenic variant in p.Leu714Gln, and three pathogenic variants in p.Leu775Valfs32, p.Thr1108Metfs8, and p.Pro5Argfs*2. : This study presents a comprehensive characterization of the targeted gene panel used for genetic analysis, while critically evaluating its diagnostic limitations within the context of contemporary genomic approaches. A pivotal accomplishment of this study was the ClinVar submission of novel de novo variants which expands the documented mutational spectrum of ASD-associated genes and enhances future diagnostic interpretation.

Fusion-Negative Rhabdomyosarcoma: Clinical Application of Targeted RNA Sequencing.
Pediatr Dev Pathol
September 2025
The Hospital for Sick Children, Division of Pathology, Toronto, Canada.
Background: Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma of childhood. For stratification purposes, rhabdomyosarcoma is classified into fusion-positive RMS (alveolar rhabdomyosarcoma) and fusion-negative RMS (embryonal or spindle cell/sclerosing, FN-RMS) subtypes according to its fusion status. This study aims to highlight the pathologic and molecular characteristics of a cohort of FN-RMS using a targeted NGS RNA-Seq assay.

Objective: The key molecular events signifying the -induced gastric carcinogenesis process are largely unknown.
Methods: Bulk tissue-proteomics profiling were leveraged across multi-stage gastric lesions from Linqu ( = 166) and Beijing sets ( = 99) and single-cell transcriptomic profiling ( = 18) to decipher key molecular signatures of -related gastric lesion progression and gastric cancer (GC) development. The association of key proteins association with gastric lesion progression and GC development were prospectively studied building on follow-up of the Linqu set and UK Biobank ( = 48,529).
Polygenic scores in Familial breast cancer cases with and without pathogenic variants and the risk of contralateral breast cancer.

Department of Immunology, Genetics and Pathology, Uppsala University, Uppsala, Sweden.
Background: Polygenic risk scores (PRS) are not yet standard in clinical risk assessments for familial breast cancer in Sweden. This study evaluated the distribution and impact of an established PRS (PRS) in women undergoing clinical sequencing for hereditary breast cancer.
Findings: We integrated PRS into a hereditary breast cancer gene panel used in clinical practice and calculated scores for 262 women.

Background: India's indigenous sheep breeds have evolved under extreme and diverse agro-ecological pressures, yet the genomic basis of their resilience and local adaptation remains poorly understood.
Method: This study combines genomic inbreeding estimates, runs of homozygosity (ROH), population structure analyses, and composite selection scans to investigate three native Indian breeds-Changthangi, Deccani, and Garole-within a panel of nine breeds that also includes populations from Africa (Ethiopian Menz), East and South Asia (Tibetan, Chinese Merino, Bangladesh Garole, Bangladesh East), and Europe (Suffolk).
Results: ROH and heterozygosity estimates revealed strong contrasts: Bangladesh East sheep exhibited high genomic inbreeding (F≈14.
Case Report: A homozygous selenocysteine insertion sequence-binding protein 2 () gene mutation in a pediatric patient.

College of Medicine, Alfaisal University, Riyadh, Saudi Arabia.
Selenocysteine insertion sequence-binding protein 2 () is crucial for the biosynthesis of selenoproteins, including iodothyronine deiodinases, which play a vital role in thyroid hormone metabolism. Mutations in can disrupt thyroid function, leading to various clinical manifestations across multiple systems. We present the case of a 3-year-old Saudi female who was referred for genetic testing due to poor growth, developmental abnormalities, and notable facial dysmorphism.
