In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition. In females (who have two X chromosomes), a mutation must be present in both copies of the gene to cause the disorder. Males are affected by X-linked recessive disorders much more frequently than females.
In 2014, a human genetic disorder (Xia-Gibbs syndrome) caused by de novo mutations in AHDC1 was discovered through whole-exome sequencing by Xia, et al. [6] Four patients were identified in the paper which recorded the initial discovery and their clinical features were reported, including global developmental delay, hypotonia, obstructive sleep apnea, intellectual disability and seizures.
Ten to fifteen genetic NBIA disorders involving various cell processes have been identified: iron metabolism, coenzyme A biosynthesis, phospholipid metabolism, ceramide metabolism, lysosomal disorders, as well as mutations in genes with unknown functions. [5] [4] Onset can occur at different ages, from early childhood to late adulthood. [4]
