Abstract

Neurodegeneration with brain iron accumulation 5 (NBIA5) is a distinctive type of NBIA phenotype that is caused by mutations in the WDR45 gene. This disorder is inherited in an X-linked manner. Here, we report three Iranian cases affected with this condition. Whole-exome sequencing revealed the following pathogenic variants within WDR45 gene in these cases, respectively: c.697 C > T (p.R233X), c.657_658del (p.F221X) and c.1004_1005del (p.Y335Cfs*5). Hypothyroidism was detected in two cases. Other clinical manifestations did not significantly differ from cases reported in the literature. All cases occurred de novo. Similar mutations have been reported in the literature. The present study broadens the insight about the genetics of this disorder in the mentioned population. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.
