Other variable and inconsistent features reported in this disorder are muscle spasms, facial dysmorphism, prenatal onset growth restriction, microphthalmia, and holoprosencephaly. This is the sixth postnatal reported patient with biallelic variants in <jats:italic>HHAT<\/jats:italic> gene, who presented with microcephaly, short stature, muscle hypertrophy, muscle spasms, and facial dysmorphism. The most prominent and presenting finding in this patient were muscle hypertrophy and muscle spasms which had a clinical response to phenytoin and acetazolamide treatment. Our report emphasizes the phenotypic variability of NNMS and further reiterates muscle spasms as an important clinical manifestation of this extremely rare condition.<\/jats:p>","DOI":"10.1002\/ajmg.a.63000","type":"journal-article","created":{"date-parts":[[2022,10,22]],"date-time":"2022-10-22T10:46:46Z","timestamp":1666435606000},"page":"238-248","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Muscle spasms as presenting feature of <scp>Nivelon\u2010Nivelon\u2010Mabile<\/scp> syndrome"],"prefix":"10.1002","volume":"191","author":[{"given":"Neelam","family":"Saini","sequence":"first","affiliation":[{"name":"Department of Medical Genetics Nizam's Institute of Medical Sciences  Hyderabad India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3318-8268","authenticated-orcid":false,"given":"Aneek","family":"Das Bhowmik","sequence":"additional","affiliation":[{"name":"Diagnostics Services (NGS) AIC \u2010 Centre for Cellular &amp;
