Added comment: NM_020151.3(STARD7):c.291-1572ATTTT[X]ATTTC[X]
158 affected individuals from 22 unrelated families with familial adult myoclonic epilepsy with a heterozygous 5-bp repeat expansion (ATTTC)n in intron 1. Affected individuals had variable expansion of an endogenous (ATTTT)n repeat in addition to the insertion of an abnormal (ATTTC)n repeat, similar molecular finding in other forms of FAME. RNA sequencing from patient derived fibroblasts shows no accumulation of the AUUUU or AUUUC repeat sequences and no effect on STARD7 gene expression, suggesting ATTTC expansions may cause FAME irrespective of the genomic locus involved.
