One of such proposed candidate genes is MRE11A. Biallelic pathogenic MRE11A germline variants cause the autosomal recessive ataxia-telangiectasia-like disorder (ATLD; OMIM #604391) which presents with a milder course than ataxia-telangiectasia. Here, MRE11 is linked to ataxia-telangiectasia-like disorder.
