Bryony Thompson (Royal Melbourne Hospital)
Complex repeat insertion (TGGAA)n, (TAGAA)n, (TAAAA)n, (TAAAATAGAA)n, TGGAA is present only in affected cases. Sequencing showed that the insertion consisted of a preceding TCAC sequence, and 3 pentanucleotide repeat components (TGGAA)n, (TAGAA)n, and (TAAAA)n in all patients tested.
2.5-3.8 KB insertion is associated with disease and RNA toxicity expected to be mechanism of disease
Normal and pathogenic cut-offs are based on animal model experiments (PMID: 31755042)
