Recently we have reported novel variant in CWF19L1 gene in a family with late-onset autosomal recessive cerebellar ataxia 17 and a novel mutation in ATM gene in a female with ataxia telangiectasia.15,16 In another study, we reported autosomal recessive cerebellar ataxia with spasticity due to a rare mutation in GBA2 gene.17 Further we also reported novel mutation in CACNA1A gene with episodic ataxia type 2 and rare mutation in the SETX gene in a Saudi patient.18,19. Here, ATM is linked to autosomal recessive cerebellar ataxia.
