X-linked Alport syndrome (XLAS) is an hereditary kidney disease caused by the pathogenic variants in COL4A5 gene and usually has heterogeneous phenotypes, especially in females. Here, we collected the genetic, clinical, and pathological data from a cohort of XLAS and conducted a comparative analysis of female and male patients. We found a higher incidence of […]

A model for the return and referral of all clinically significant secondary findings of genomic sequencing
Genomic sequencing (GS) has the capability of identifying a broad range of clinically significant secondary findings (SFs) beyond medically actionable findings. Healthcare resources and capacity constraints of returning and managing all clinically significant SFs represent major barriers to implementation of GS. We present a model for the return and referral of all clinically significant SFs […]
Craniofacial features of POLR3-related leukodystrophy caused by biallelic variants in POLR3A, POLR3B and POLR1C
RNA polymerase III-related or 4H (POLR3-HLD) is a genetic disorder that affects the white matter of the brain. It is caused by disease-causing variants in POLR3A, POLR3B, POLR1C or POLR3K. To this date, description of craniofacial features in individuals with POLR3-HLD is limited. Here, we explore and assess the craniofacial features of 31 patients with […]
Pulmonary function and structure abnormalities in children and young adults with osteogenesis imperfecta point to intrinsic and extrinsic lung abnormalities
Lung disease is the major cause of illness and death in individuals with osteogenesis imperfecta (OI), a collagen-related bone disorder. Previously, scoliosis and chest wall deformities were considered responsible for abnormal lung function in OI. We studied children and adults with several types of OI using lung function tests, X-Rays and lung CTs. Most patients […]
The phenotypic differences of C9ORF72 gene positive and negative amyotrophic lateral sclerosis: A comparative case series
Amyotropic lateral sclerosis (ALS) is the commonest form of motor neuron disease, with some cases caused by mutations in the C9ORF72 gene. At our tertiary neurosciences clinic, we compared a group of ALS patients with the C9ORF72 mutation to a group without the mutation. Patients with the C9ORF72 mutation were more likely to present with […]
Variants in the gene DNA2 causes Rothmund-Thomson syndrome-like presentation
Rothmund-Thomson syndrome is a rare genetic disorder caused by variants in both copies of ANAPC1 or RECQL4 genes. We report on six Brazilian individuals and two siblings of Swiss/Portuguese ancestry who presented severe short stature, poikiloderma and congenital ocular anomalies. Genomic analysis revealed that all patients harbored variants in both copies of DNA2, one variant, […]
Early breast cancer risk detection: a novel framework leveraging polygenic risk scores and machine learning
Despite great progress in the identifications of genes associated with breast cancer, there is still limited use of such knowledge in breast cancer (BC) screening, with nearly one-third of BC patients still missing the early detection phase. We have developed BRECARDA, an AI-based framework that incorporates genetic information and clinical risk factors to predict breast […]
Strategic validation of variants of uncertain significance in ECHS1 genetic testing
Nowadays, genetic testing can provide an accurate diagnosis for hereditary disorders in general practice. Currently, the accumulation of variants of unknown significance (VUSs) during genetic testing is a major problem and rate-limiting step in genetic diagnosis. This study provides a novel and high-throughput methodology to solve this problem and promotes rapid evaluations of VUSs. Further […]
Germline (epi)genetics reveals high predisposition in females: a 5-year, nationwide, prospective Wilms tumour cohort
Wilms tumors, a rare form of kidney cancer that typically affects children, can be caused by high-penetrance genetic or epigenetic factors. However, studies systematically examining both these aspects of the disease are scarce. In a new study, researchers offered germline whole-genome sequencing to all participants diagnosed with Wilms tumors from 2016 to 2021 in Denmark. […]
Validation and depth evaluation of low-pass genome sequencing in prenatal diagnosis using 387 amniotic fluid samples
Low-pass genome sequencing (LP GS) has been widely used in CNV detection andis considered as an alternative to chromosomal microarray analysis. However, application of LP GS as a first-line prenatal diagnostic test is not ready.The increase in sequencing depth will improve detection sensitivity, followed by the increase for cost. This could greatly block the successful […]
