To capture the full spectrum of genetic risk for autism, we performed a two-stage analysis of rare de novo and inherited coding variants in 42,607 autism cases, including 35,130 new cases recruited online by SPARK. We identified 60 genes with exome-wide significance (P < 2.5 × 10), including five new risk genes (NAV3, ITSN1, MARK2, SCAF1 and HNRNPUL2). The association of NAV3 with autism risk is primarily driven by rare inherited loss-of-function (LoF) variants, with an estimated relative risk of 4, consistent with moderate effect. Autistic individuals with LoF variants in the four moderate-risk genes (NAV3, ITSN1, SCAF1 and HNRNPUL2; n = 95) have less cognitive impairment than 129 autistic individuals with LoF variants in highly penetrant genes (CHD8, SCN2A, ADNP, FOXP1 and SHANK3) (59% vs 88%, P = 1.9 × 10). Power calculations suggest that much larger numbers of autism cases are needed to identify additional moderate-risk genes.

Background: Developmental and epileptic encephalopathies (DEEs) comprise a diverse range of disorders that can arise from both genetic and non-genetic causes. Genetic DEEs are linked to pathogenic variants in various genes with different molecular functions. The wide clinical and genetic variability found in DEEs poses a considerable challenge for accurate diagnosis even with the use of comprehensive diagnostic approaches such as whole genome sequencing (WGS).

Objective: This study investigates the association between alobar holoprosencephaly (HPE) and de novo germline microdeletions in the Xq25 region. To develop a Preimplantation Genetic Testing for Monogenic Disorders (PGT-M) based workflow enabling high-resolution preimplantation detection of sub-Mb microdeletions, overcoming the >1 Mb resolution limit of conventional whole genome amplification(WGA) copy number variation(CNV) sequencing to identify causative Xq25 variants and prevent pathogenic microdeletion transmission.
Methods: This study presents a clinical case involving a couple with an adverse obstetric history accompanied by two occurrences of HPE.

The aim of this study was to investigate three unrelated Simmental calves with atypical white coat color, identify potential genetic causes using a trio-based whole-genome sequencing approach, and assess the prevalence of the identified variants in the breed. Several inherited alleles affecting coat color, ranging from fawn to red spotted and white-headed, have been described in Simmental cattle originating from Switzerland. However, no genetic variant has yet been associated with an almost completely white coat in this breed.

Introduction: Clinical Dementia Rating Sum of Boxes (CDR-SB) is a reliable and clinically meaningful composite for assessing treatment effects in Alzheimer's disease (AD) clinical trials. Small CDR-SB differences at the end of a trial often lead to controversy in deriving clinically meaningful interpretations.
Methods: We estimated progression-free time (PFT) participants remained at each 0.

Background: Sickle cell disease (SCD) is a chronic inherited blood disorder caused by abnormal haemoglobin production, affecting over seven million people worldwide. Although pain-particularly acute bone pain-is the hallmark symptom of this disease, fatigue is also a commonly observed manifestation. Fatigue is a debilitating symptom in Sickle Cell Disease (SCD) that significantly impacts quality of life.
