BACKGROUND: GEMIN5 is an RNA-binding protein that regulates multiple molecular functions, including splicing, localisation, translation, and mRNA stability. GEMIN5 mutations present a syndrome centred on cerebellar dysplasia, including motor dysfunction, developmental delay, cerebellar atrophy, and hypotonia.
CASES: We report three patients from two families with novel compound heterozygous mutations in the tetratricopeptide repeat-like domain of the GEMIN5 gene who presented with motor dysfunction, developmental delay, and ataxia syndrome. Novel variants were identified: c.2551_c.2552delCT (Leu851Glufs*30) and c.2911 C > G (Gln971Glu) in Family 1, and c.3287 T > C (Leu1096Pro) and c.2882 G > C (Trp961 Ser) in Family 2, which were inherited from their parents. Moreover, infantile spasms syndrome(ISs) was diagnosed in the family.
CONCLUSION: We report the first case of ISs caused by GEMIN5 gene mutations. Our cases expand on GEMIN5 variants and neurological phenotypes, reinforcing the crucial impact of tetratricopeptide repeat-like domain variants in the GEMIN5 gene.
