Motivation: Improvements in next-generation sequencing have enabled genome-based diagnosis for patients with genetic diseases. However, accurate interpretation of human variants requires knowledge from a number of clinical cases. In addition, manual analysis of each variant detected in a patient's genome requires enormous time and effort. To reduce the cost of diagnosis, various computational tools have been developed to predict the pathogenicity of human variants, but the shortage and bias of available clinical data can lead to overfitting of algorithms.
Results: We developed a pathogenicity predictor, 3Cnet, that uses recurrent neural networks to analyze the amino acid context of human variants. As 3Cnet is trained on simulated variants reflecting evolutionary conservation and clinical data, it can find disease-causing variants in patient genomes with 2.2 times greater sensitivity than currently available tools, more effectively discovering pathogenic variants and thereby improving diagnosis rates.
Availability And Implementation: Codes (https://github.com/KyoungYeulLee/3Cnet/) and data (https://zenodo.org/record/4716879#.YIO-xqkzZH1) are freely available to non-commercial users.
Supplementary Information: Supplementary data are available at Bioinformatics online.

Background: Mutations in gamma-secretase complex (GSC) genes are associated with hidradenitis suppurativa (HS), and toll-like receptor (TLR) 2 is elevated in HS lesions. However, it remains unclear whether TLR2 is upregulated in the skin lesions of patients with HS with GSC gene variants, and the role of its upregulation in the pathogenesis of this disease are unknown.
Objective: To investigate the role of TLR2 upregulation in NCSTN and PSENEN knockdown keratinocytes.

Human succinic semialdehyde dehydrogenase is a mitochondrial enzyme fundamental in the neurotransmitter γ-aminobutyric acid catabolism. It catalyzes the NAD-dependent oxidative degradation of its derivative, succinic semialdehyde, to succinic acid. Mutations in its gene lead to an inherited neurometabolic rare disease, succinic semialdehyde dehydrogenase deficiency, characterized by mental and developmental delay.

Objectives: Biallelic HPDL variants have been identified as the cause of a progressive childhood-onset movement disorder, with a broad clinical spectrum from severe neurodevelopmental disorder to juvenile-onset pure hereditary spastic paraplegia type 83. This study aims at delineating the geno- and phenotypic spectra of patients with HPDL-related disease, quantitatively modelling the natural history, and uncovering genotype-phenotype associations.
Methods: A cross-sectional analysis of 90 published and one novel case was performed, employing a Human Phenotype Ontology-based approach.
