Fragile X syndrome (FXS) is a genetic disorder caused by a mutation in the fragile X messenger ribonucleoprotein 1 ( FMR1 ) gene and known to be a leading cause of inherited intellectual disability globally. It results in a range of intellectual, developmental, and behavioral problems. Fragile X premutation-associated conditions (FXPAC), caused by a smaller CGG expansion (55 to 200 CGG repeats) in the FMR1 gene, are linked to other conditions that increase morbidity and mortality for affected persons. Limited research has been conducted on the burden, characteristics, diagnosis, and management of these conditions in Africa. This comprehensive review provides an overview of the current literature on FXS and FXPAC in Africa. The issues addressed include epidemiology, clinical features, discrimination against affected persons, limited awareness and research, and poor access to resources, including genetic services and treatment programs. This paper provides an in-depth analysis of the existing worldwide data for the diagnosis and treatment of fragile X disorders. This review will improve the understanding of FXS and FXPAC in Africa by incorporating existing knowledge, identifying research gaps, and potential topics for future research to enhance the well-being of individuals and families affected by FXS and FXPAC.

Fragile X syndrome (FXS) is a significant cause of intellectual disability and autism, while Fragile X Premutation ‐Associated Conditions (FXPAC) are a significant cause of morbidity and mortality globally. This study assessed the level of knowledge and perceptions about FXS and FXPAC among doctors in Nigeria. It was a web‐based, cross‐sectional study conducted among a cohort of doctors in Nigeria. Socio‐demographic profile, knowledge of FXS, perceptions about FXS, knowledge of FXPAC, experience of doctors, and suggested ways of improving knowledge and management of FXS were obtained. Data were analyzed using STATA 16.0. Chi‐square and Fisher's exact tests of association were used to determine the association between variables, with the significance level set at p < 0.05. A total of 274 doctors participated in the study. A significant proportion of respondents had limited knowledge about the clinical features of FXS. Nine of ten (90.0%) participants with good knowledge of FXS had good perceptions of FXS management. This was statistically significant (p < 0.001). There was a high nonresponse rate to what FXPAC is (164/274, 59.9%) among the respondents because of insufficient knowledge. Suboptimal knowledge of FXS which influenced perception was noted among doctors. More strategies should be considered to improve doctors' knowledge and management of FXS and FXPAC in Nigeria.
