The related phenotype is mainly characterized by abnormal thermoregulation and sweating, facial muscle contractions in response to tactile and crying-inducing stimuli at an early age, skeletal anomalies (camptodactyly of the hands, scoliosis), and craniofacial dysmorphisms, comprising full cheeks, micrognathia, high and narrow palate, low-set ears, and a depressed nasal bridge. The condition is associated with high lethality during the neonatal period and can benefit from timely symptomatic therapy. Methods: We collected frontal images of all patients with CISS1\/CISS published to date, which were analyzed with Face2Gene (F2G), a machine-learning technology for the facial diagnosis of syndromic phenotypes. In total, 75 portraits were subdivided into three cohorts, based on age (Cohort 1 and 2) and the presence of the typical facial trismus (Cohort 3). These portraits were uploaded to F2G to test their suitability for facial analysis and to verify the capacity of the AI tool to correctly recognize the syndrome based on the facial features only. The photos which passed this phase (62 images) were fed to three different AI algorithms\u2014DeepGestalt, Facial D-Score, and GestaltMatcher. Results: The DeepGestalt algorithm results, including the correct diagnosis using a frontal portrait, suggested a similar facial phenotype in the first two cohorts. Cohort 3 seemed to be highly differentiable. The results were expressed in terms of the area under the curve (AUC) of the receiver operating characteristic (ROC) curve and p Value. The Facial D-Score values indicated the presence of a consistent degree of dysmorphic signs in the three cohorts, which was also confirmed by the GestaltMatcher algorithm. Interestingly, the latter allowed us to identify overlapping genetic disorders. Conclusions: This is the first AI-powered image analysis in defining the craniofacial contour of CISS1\/CISS and in determining the feasibility of training the tool used in its clinical recognition. The obtained results showed that the use of F2G can reveal valid support in the diagnostic process of CISS1\/CISS, especially in more severe phenotypes, manifesting with facial contractions and potentially lethal consequences.<\/jats:p>","DOI":"10.3390\/diagnostics15050521","type":"journal-article","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T03:47:46Z","timestamp":1740109666000},"page":"521","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["An Artificial Intelligence Approach to the Craniofacial Recapitulation of Crisponi\/Cold-Induced Sweating Syndrome 1 (CISS1\/CISS) from Newborns to Adolescent Patients"],"prefix":"10.3390","volume":"15","author":[{"given":"Giulia","family":"Pascolini","sequence":"first","affiliation":[{"name":"Genetic Counselling Unit, Istituto Dermopatico Dell\u2019immacolata, IDI-IRCCS, Via dei Monti di Creta 104, 00167 Rome, Italy"},{"name":"Rare Diseases Center, Istituto Dermopatico Dell\u2019immacolata, IDI-IRCCS, 00167 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6119-1870","authenticated-orcid":false,"given":"Dario","family":"Didona","sequence":"additional","affiliation":[{"name":"Rare Diseases Center, Istituto Dermopatico Dell\u2019immacolata, IDI-IRCCS, 00167 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5958-9364","authenticated-orcid":false,"given":"Luigi","family":"Tarani","sequence":"additional","affiliation":[{"name":"Department of Maternal Infantile and Urological Sciences, Sapienza University, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"971","DOI":"10.1086\/516843","article-title":"Crisponi syndrome is caused by mutations in the CRLF1 gene and is allelic to cold-induced sweating syndrome type 1","volume":"80","author":"Crisponi","year":"2007","journal-title":"Am.
