Neurogenic arthrogryposis due to SCYL2 mutations, also known as arthrogryposis multiplex congenita 4 (AMC4), is a rare condition that presents with microcephaly, agenesis of the corpus callosum, optic atrophy, global developmental delay, and early lethality. We used whole-exome sequencing to identify pathogenic variants, DynaMut2 to determine the predicted effect on protein stability, and Western blot to investigate the effect on protein expression. We present two novel missense mutations in SCYL2 resulting in loss of function at the protein level in a pediatric case of AMC4, further highlighting the key role of SCYL2 in neuronal cell survival and healthy brain development. There is diversity in the pathological features among previously published cases of AMC4, most likely due to the nature of each mutation. This report summarizes the clinical data of all known patients with SCYL2 mutations.<\/jats:p>","DOI":"10.3390\/ijms26073079","type":"journal-article","created":{"date-parts":[[2025,3,28]],"date-time":"2025-03-28T04:11:40Z","timestamp":1743135100000},"page":"3079","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Novel SCYL2 Mutations and Arthrogryposis Multiplex Congenita 4: Case Report and Review of the Literature"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8694-4699","authenticated-orcid":false,"given":"Khaled","family":"Zamel","sequence":"first","affiliation":[{"name":"Division of Pediatric Neurology, Department of Pediatrics, Sidra Medicine, Doha 26999, Qatar"},{"name":"Department of Clinical Pediatrics, Weill-Cornell Medical College, Doha 24144, Qatar"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8521-8153","authenticated-orcid":false,"given":"Abdulrahman Ahmed","family":"Al-Subaiey","sequence":"additional","affiliation":[{"name":"Research Department, Sidra Medicine, Doha 26999, Qatar"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohamed","family":"Alsabbagh","sequence":"additional","affiliation":[{"name":"Research Department, Sidra Medicine, Doha 26999, Qatar"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8489-1335","authenticated-orcid":false,"given":"Abeer","family":"Fadda","sequence":"additional","affiliation":[{"name":"Research Department, Sidra Medicine, Doha 26999, Qatar"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amira","family":"Saeed","sequence":"additional","affiliation":[{"name":"Research Department, Sidra Medicine, Doha 26999, Qatar"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bruno","family":"Mourao Pacheco","sequence":"additional","affiliation":[{"name":"Department of Clinical Pediatrics, Weill-Cornell Medical College, Doha 24144, Qatar"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1087-6845","authenticated-orcid":false,"given":"Bernice","family":"Lo","sequence":"additional","affiliation":[{"name":"Research Department, Sidra Medicine, Doha 26999, Qatar"},{"name":"College of Health and Life Sciences, Hamad Bin Khalifa University, Doha 34110, Qatar"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7829-8722","authenticated-orcid":false,"given":"Ruba","family":"Benini","sequence":"additional","affiliation":[{"name":"Division of Pediatric Neurology, Department of Pediatrics, Sidra Medicine, Doha 26999, Qatar"},{"name":"Department of Clinical Pediatrics, Weill-Cornell Medical College, Doha 24144, Qatar"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"599","DOI":"10.12688\/f1000research.7134.1","article-title":"Advances in understanding\u2014Genetic basis of intellectual disability","volume":"5","author":"Chiurazzi","year":"2016","journal-title":"F1000Research"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"268","DOI":"10.1038\/s41586-018-0566-4","article-title":"Common genetic variants contribute to risk of rare severe neurodevelopmental disorders","volume":"562","author":"Niemi","year":"2018","journal-title":"Nature"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1038\/s12276-018-0129-7","article-title":"Genomics in neurodevelopmental disorders: An avenue to personalized medicine","volume":"50","author":"Tarlungeanu","year":"2018","journal-title":"Exp.
