Although it is one of the oldest inherited metabolic disorders, new genetic methods and long-time patient follow-ups provide us with unique insight into the genotype\u2013phenotype correlations. The aim of this study was to share the phenotypic features and molecular diagnostic results that include new pathogenic variants in our GSD cases. Twenty-six GSD patients were evaluated retrospectively. Demographic data, initial laboratory and imaging features, and current findings of the patients were recorded. Molecular analysis results were classified as novel or previously defined variants. Novel variants were analyzed with pathogenicity prediction tools according to American College of Medical Genetics and Genomics (ACGM) criteria. Twelve novel and rare variants in six different genes were associated with the disease. Hearing impairment in two patients with GSD I, early peripheral neuropathy after liver transplantation in one patient with GSD IV, epilepsy and neuromotor retardation in three patients with GSD IXA were determined. We characterized a heterogeneous group of all diagnosed GSDs over a 5-year period in our institution, and identified novel variants and new clinical findings. It is still difficult to establish a genotype\u2013phenotype correlation in GSDs.<\/jats:p>","DOI":"10.3390\/genes12121987","type":"journal-article","created":{"date-parts":[[2021,12,14]],"date-time":"2021-12-14T22:06:10Z","timestamp":1639519570000},"page":"1987","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Evaluation of Glycogen Storage Patients: Report of Twelve Novel Variants and New Clinical Findings in a Turkish Population"],"prefix":"10.3390","volume":"12","author":[{"given":"Melike","family":"Ersoy","sequence":"first","affiliation":[{"name":"Division of Pediatric Metabolic Diseases, Department of Pediatrics, Bakirkoy Dr. Sadi Konuk Training and Research Hospital, University of Health Sciences, Istanbul 34093, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bulent","family":"Uyanik","sequence":"additional","affiliation":[{"name":"Division of Medical Genetics, Department of Internal Medicine, Faculty of Medicine, Bezmialem Foundation University, Istanbul 34093, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Asuman","family":"Gedikbasi","sequence":"additional","affiliation":[{"name":"Division of Medical Genetics, Department of Pediatric Basic Sciences, Institute of Child Health, Istanbul University, Istanbul 34104, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2541","DOI":"10.3748\/wjg.v13.i18.2541","article-title":"Glycogen storage diseases: New perspectives","volume":"13","year":"2007","journal-title":"World J.
