Tooth agenesis is described as the absence of one or more teeth. It is caused by a failure in tooth development and is one of the most common human developmental anomalies. We herein report genomic analyses of selective mandibular incisor agenesis (SMIA) using exome sequencing. Two Japanese families with SMIA were subjected to exome sequencing, and family with sequence similarity 65 member A (), nuclear factor of activated T-cells 3 () and cadherin-related 23 gene () were detected. In the follow-up study, 51 Japanese and 32 Korean sporadic patients with SMIA were subjected to exome analyses, and 18 reported variants in , , , , , and and 27 variants of , and were found in 38 patients. Our comprehensive genetic study of SMIA will pave the way for a full understanding of the genetic etiology of SMIA and provide targets for treatment.

Background: Alzheimer's disease (AD) is a progressive neurodegenerative disorder with both genetic and environmental factors contributing to its pathogenesis. While early-onset AD has well-established genetic determinants, the genetic basis for late-onset AD remains less clear. This study investigates a large Italian family with late-onset autosomal dominant AD, identifying a novel rare missense variant in GRIN2C gene associated with the disease, and evaluates the functional impact of this variant.

Autosomal dominant deafness-15 which is caused by mutation in the POU4F3 gene, has been reported with a wide degree of clinical heterogeneity, even between intrafamilial members. However, the reason is still elusive. In this study, A four-generation Chinese family with 11 patients manifesting late-onset progressive non-syndromic hearing loss was recruited.

Next-generation sequencing (NGS) offers a promising approach for differentiating multiple primary lung cancers (MPLC) from intrapulmonary metastasis (IPM), though panel selection and clonal interpretation remain challenging. Whole-exome sequencing (WES) data from 80 lung cancer samples were utilized to simulate MPLC and IPM, with various sequenced panels constructed through gene subsampling. Two clonal interpretation approaches primarily applied in clinical practice, MoleA (based on shared mutation comparison) and MoleB (based on probability calculation), were subsequently evaluated.

In monogenic diseases, double mosaic variants of the same gene have rarely been identified. Here, we report the case of triple mosaic variants in PURA, a gene responsible for a neurodevelopmental syndrome (OMIM# 616158). Whole-exome sequencing identified three somatic PURA variants in our case with a similar neurodevelopmental syndrome: NM_005859.

Investigating the genetic factors influencing human birth weight may lead to biological insights into fetal growth and long-term health. We report analyses of rare variants that impact birth weight when carried by either fetus or mother, using whole exome sequencing data in up to 234,675 participants. Rare protein-truncating and deleterious missense variants are collapsed to perform gene burden tests.
