The clinical data and molecular genetic test results of a child with SMS caused by a novel mutation in the retinoic acid-induced-1 (RAI1) gene were reviewed. A female patient aged 12 years and 9 months presented to the clinic because her mental and motor development was lagging behind that of her peers. The child had learning difficulties, poor motor coordination, temper tantrums, and self-injurious behaviors, such as skin scratching. She had a peculiar facial appearance, dry skin with scattered eczema, low hairline, wide forehead, flat face, collapsed nasal bridge, turned out upper lip, and deep palmar lines on the right hand through the palm. Wechsler\u2019s IQ test score was 48. Her electroencephalogram was normal. The diagnosis of SMS was confirmed by a heterozygous mutation in exon 3 of the RAI1 gene on chromosome chr-1717696650 at locus c.388C&gt;T (P.Q130X). In addition, this patient had severe eczema on the skin. The RAI1 mutation c.388C&gt;T (P.Q130X) is a newly reported variant that will help in the clinical identification of SMS and the precise localization of more phenotypically related genes.<\/jats:p>","DOI":"10.1177\/03000605231190553","type":"journal-article","created":{"date-parts":[[2023,9,27]],"date-time":"2023-09-27T15:33:51Z","timestamp":1695828831000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["A
