The ATRX splicing variant c.21-1G>A is asymptomatic

[摘要] The ATRX variant c.21-1G>A was detected by an exome analysis of a patient with Cockayne syndrome without alpha thalassemia X-linked intellectual disability syndrome (ATR-XS). In addition, variants in ERCC6 were detected. ATRX c.21-1G>A is localized at the splicing acceptor site of intron 1. This splicing event, NM_000489.6: c.21_133del p.S7Rfs*1, induces exon 2 deletion and early termination. The start codon in exon 3 of ATRX is presumed to produce a slightly shorter but functional ATRX protein.
