Objective The current study delves into the accessibility of genetic evaluations for individuals with orofacial clefts (OC), comparing data between genetics and treatment centers across Brazil. Methods This cross-sectional retrospective study analyzed primary data from 1463 OC individuals registered in the Brazilian Database of Craniofacial Anomalies (BDCA) between 2008 and 2018 without age or sex selection. Diagnostic exam results stemming from research projects until 2023 were considered. Results Of the 1463 individuals with typical OC, 987 were non-syndromic, 462 were syndromic (SOC), 10 presented atypical forms, and three were not specified OC cases. The average age for accessing laboratory diagnosis was 8.5 years among SOC individuals. Notably, more SOC cases were registered in genetics centers than treatment and rehabilitation centers (37.1 % vs. 29 %, p = 0.0015). Those originating from genetics centers accessed diagnosis at an average age of 7.3 years, while those from treatment and rehabilitation centers experienced delays with an average age of 10.7 years (p = 0.0581). Conclusions Irrespective of the center of origin, the data highlight delayed diagnosis and challenges in accessing genetic tests for the syndromic group. Given the widespread reliance on the public health system by most of the Brazilian population, disseminating this data can significantly contribute to shaping an informed perspective on healthcare access. These insights can improve public policies tailored to the unique needs of individuals with OC. [ABSTRACT FROM AUTHOR]

Objectives: The aim of this study was to describe clinical features in subjects with palatal abnormalities and to assess the distribution of these features among those with and without 22q11.2 deletion. Design: Descriptive cohort. Patients: One hundred patients with palatal abnormalities and suspicion of 22q11.2 DS were included. Methods: All patients were evaluated by a clinical geneticist, who completed a standardized clinical protocol. The 22q11.2 deletion screening was performed with fluorescence in situ hybridization using the TUPLE1 probe and multiplex ligation-dependent probe amplification using the P250-A1 kit. Results: The 22q11.2 deletion was detected in 35 patients, in whom the most frequent clinical features were congenital heart disease (15/30 - 50%), developmental delay (19/35 - 54%), speech delay (20/35 57%), learning disabilities (27/35 - 77%), immunologic alterations (18/29 62%). In addition, the most common facial dysmorphisms in this group were long face (27/35 - 77%), typical nose (24/35 - 69%), and hooded eyelids (19/35 - 54%). Comparing features in patients with or without the deletion revealed significant differences (positively correlated with the deletion) for speech delay, learning disabilities, conductive hearing loss, number of dysmorphisms, long face, and hooded eyelids. Cleft lip and palate was negatively correlated with the deletion. Conclusions: The presence of speech delay, learning disabilities, conductive hearing loss, long face, and hooded eyelids should reinforce the suspicion of 22q11.2 DS in patients with palatal abnormalities and would help professionals direct clinical follow-up of these patients.
