X-linked creatine deficiency mainly affects males because the SLC6A8 gene is located on the X chromosome.

The deficiency of creatine can lead to a range of clinical symptoms and health problems. These symptoms can include intellectual disability, delayed speech and language development, seizures, autistic behaviors, and movement disorders. In addition to these core symptoms, some individuals with X-linked creatine deficiency may also have other related health issues.

The scientific literature provides additional information on this condition, its genetic changes, and clinical aspects. A variety of resources like PubMed, OMIM, and GENET can be used to gather more information on X-linked creatine deficiency. The Online Mendelian Inheritance in Man (OMIM) database lists information about genes and genetic conditions, including X-linked creatine deficiency.

In terms of diagnosis, genetic testing can be performed to identify mutations in the SLC6A8 gene. Family testing can also be conducted to identify carrier females and offer genetic counseling.
