AB Despite new strategies, such as evaluating deep intronic variants and new genes inwhole-genome-sequencing studies, the diagnostic yield of genetic testing in hypertrophiccardiomyopathy (HCM) is still around 50%. FHOD3 has emerged as a noveldisease-causing gene for this phenotype, but the relevance and clinical implication ofcopy-number variations (CNVs) have not been determined. In this study, CNVs wereevaluated using a comparative depth-of-coverage strategy by next-generationsequencing (NGS) in 5493 HCM probands and 2973 disease-controls. We detectedthree symmetrical deletions in FHOD3 that involved exons 15 and 16 in three HCMfamilies (no CNVs were detected in the control group). These exons are part of thediaphanous inhibitory domain of FHOD3 protein, considered a cluster of mutationsfor HCM. The clinical characteristics of the affected carriers were consistent withthose reported in FHOD3 in previous studies. This study highlights the importance ofperforming CNV analysis systematically in NGS genetic testing panels for HCM, andreinforces the relevance of the FHOD3 gene in the disease.
