Genomic medicine programs of various sizes have been developed with the aim of identifying individuals with elevated genetic risk for multiple diseases. In this issue, O ’Brien et al. introduce and report the initial results of the Healthy Oregon Project (HOP), a statewide genomic medicine program focused on hereditary cancer and hypercholesterolemia. The authors discuss several practical aspects of developing and implementing a low-cost, yet highly effective, pr ogram, including sample collection protocol, development of a custom gene panel, laboratory innovations, quality control, and return of results.

High-throughput functional dissection of noncoding SNPs with biased allelic enhancer activity for insulin resistance-relevant phenotypes
We systematically identified 876 functional SNPs associated with insulin resistance-relevant phenotypes and prioritized 102 candidate target genes by multi-omics analyses. Specifically, we decrypted the genetic regulatory mechanism underlying IRS1 locus. Based on the STARR-seq data, we predicted the regulatory activities of over 200,000 noncoding SNPs and developed an open resource. (Source: The American Journal of Human Genetics)

An allelic-series rare-variant association test for candidate-gene discovery
Allelic series are collections of variants that lead to a gradation of possible phenotypes. We introduce COAST (Coding-Variant Allelic-Series Test), a test that identifies genes where increasingly deleterious mutations have increasing phenotypic effects. We apply COAST to uncover genes harboring allelic series for lipid and cell-count traits in the UK Biobank. (Source: The American Journal of Human Genetics)

A form of inherited hyperferritinemia associated with bi-allelic pathogenic variants of STAB1
Hyperferritinemia is a frequent finding in several conditions, both genetic and acquired. We previously studied eleven healthy subjects from eight different families presenting with unexplained hyperferritinemia. Their findings suggested the existence of an autosomal-recessive disorder. We carried out whole-exome sequencing to detect the genetic cause of hyperferritinemia. Immunohistochemistry and flow cytometry assays were performed on liver biopsies and monocyte-macrophages to confirm the pathogenic role of the identified candidate variants.

Genotype error due to low-coverage sequencing induces uncertainty in polygenic scoring
Petter et  al. investigate the impact of genotyping error on the accuracy of polygenic scores (PGSs). The study takes a probabilistic approach to create individual PGS credible intervals accounting for the genotype errors and explores the use of such credible intervals for enhanced PGS-based risk stratificat ion.

Monoallelic variation in DHX9, the gene encoding the DExH-box helicase DHX9, underlies neurodevelopment disorders and Charcot-Marie-Tooth disease
Calame et  al. describe 20 individuals with monoallelic rare damaging DHX9 variants and neurologic phenotypes ranging from severe neurodevelopmental disorders to adult-onset Charcot-Marie-Tooth disease. Functional studies show that DHX9 variants disrupt DHX9 cellular localization and helicase activity and in crease R-loops and double-stranded DNA breaks.

De novo missense variants in phosphatidylinositol kinase PIP5KI γ underlie a neurodevelopmental syndrome associated with altered phosphoinositide signaling
We describe a neurodevelopmental disorder associated with de novo gain-of-function variants in PIP5KI γ kinase. The variants cause perturbed endosomal function resulting from increased production of phosphatidylinositol 4,5 bisphosphate and enhanced association of F-actin at endosomes. Moreover, mutant zebrafish larvae recapitulate the phenotypes observed in affected individuals from our cohort. (Source: The American Journal of Human Genetics)

Genetic underpinning of the comorbidity between type 2 diabetes and osteoarthritis
Multimorbidity is a rising public health challenge. Here, we study the genetic underpinning of the comorbidity between type 2 diabetes and osteoarthritis and provide insights into its biological basis. The approach can be applied to any pair of co-occurring diseases. (Source: The American Journal of Human Genetics)

Stretch-activated ion channel TMEM63B associates with developmental and epileptic encephalopathies and progressive neurodegeneration
Combining in silico evaluation, in  vitro electrophysiology and Ca2+ imaging, and in vivo modeling in Drosophila, Vetro et al. demonstrate that gain-of-function variants of the stretch-activated ion channel TMEM63B cause a severe neurodevelopmental disorder with early-onset epilepsy and progressive brain damage associated with hem atological abnormalities in most individuals.

Response to Li and Hopper
To the Editor: We are thankful for and appreciate the interest shown by Li and Hopper toward our study.1 Our main aim was to answer with systematic evaluations the question frequently encountered with translational research of polygenic risk scores (PRSs): why do we need PRSs if we have information on family history? Surveying family history has been a part of clinical risk estimation in many diseases for decades, making the question highly relevant as genetic profiling data becomes commonly available.

Implications of family history and polygenic risk scores for causation
To the Editor: Mars and colleagues1 investigated the risk associations of having a family history, and of a genome-wide polygenic risk score (PRS), for 24 common diseases using the extraordinary FinnGen resource. They first estimated the marginal associations and then the conditional associations by fitting both family history and PRS together. Creatively, they did this separately for family history defined by first- and by second-degree relatives, and the results differed. We believe that their analyses have important implications for understanding both the causes of familial aggregation and the causes of the diseases the...
