Here we present two additional patients with hypertrophic cardiomyopathy caused by biallelic variants in ALPK3. Genetic investigation was performed using a targeted gene panel consisting of known cardiomyopathy-associated genes and whole exome sequencing. The patients showed a large difference in the age of onset, and both presented with extracardiac features that are often seen in ALPK3 patients. The patient with the later onset showed milder extracardiac symptoms, such as decreased muscle tone and distal muscular dystrophy, but had fast progression of cardiac complications leading to the need of heart transplantation. This study further elucidates the variability of both symptoms and age of onset among these patients.<\/jats:p>","DOI":"10.3390\/genes11101201","type":"journal-article","created":{"date-parts":[[2020,10,15]],"date-time":"2020-10-15T21:42:21Z","timestamp":1602798141000},"page":"1201","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Two New Cases of Hypertrophic Cardiomyopathy and Skeletal Muscle Features Associated with ALPK3 Homozygous and Compound Heterozygous Variants"],"prefix":"10.3390","volume":"11","author":[{"given":"John","family":"Jorholt","sequence":"first","affiliation":[{"name":"Department of Women\u2019s and Children\u2019s Health and Center for Molecular Medicine, Karolinska Institute, 17177 Stockholm, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yulia","family":"Formicheva","sequence":"additional","affiliation":[{"name":"Almazov National Medical Research Centre, Saint Petersburg 197341, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tatyana","family":"Vershinina","sequence":"additional","affiliation":[{"name":"Almazov National Medical Research Centre, Saint Petersburg 197341, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Artem","family":"Kiselev","sequence":"additional","affiliation":[{"name":"Almazov National Medical Research Centre, Saint Petersburg 197341, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexey","family":"Muravyev","sequence":"additional","affiliation":[{"name":"Almazov National Medical Research Centre, Saint Petersburg 197341, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elena","family":"Demchenko","sequence":"additional","affiliation":[{"name":"Almazov National Medical Research Centre, Saint Petersburg 197341, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Petr","family":"Fedotov","sequence":"additional","affiliation":[{"name":"Almazov National Medical Research Centre, Saint Petersburg 197341, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Zlotina","sequence":"additional","affiliation":[{"name":"Almazov National Medical Research Centre, Saint Petersburg 197341, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anton","family":"Rygkov","sequence":"additional","affiliation":[{"name":"Almazov National Medical Research Centre, Saint Petersburg 197341, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elena","family":"Vasichkina","sequence":"additional","affiliation":[{"name":"Almazov National Medical Research Centre, Saint Petersburg 197341, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Sejersen","sequence":"additional","affiliation":[{"name":"Department of Women\u2019s and Children\u2019s Health and Center for Molecular Medicine, Karolinska Institute, 17177 Stockholm, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Kostareva","sequence":"additional","affiliation":[{"name":"Department of Women\u2019s and Children\u2019s Health and Center for Molecular Medicine, Karolinska Institute, 17177 Stockholm, Sweden"},{"name":"Almazov National Medical Research Centre, Saint Petersburg 197341, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,10,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"41","DOI":"10.1038\/jhg.2015.83","article-title":"Molecular genetics and pathogenesis of cardiomyopathy","volume":"61","author":"Kimura","year":"2016","journal-title":"J.
