Figure 2

Single exon in-frame deletion within the FERM domain of CCM1. (A) Contrast-enhanced T1-weighted MR showing two left temporal cavernomas (white arrowheads) causing drug-resistant epilepsy in a 46-year-old female (upper left panel). Intraoperative view after resection of the two temporal cavernomas and their surrounding hemosiderin (upper right panel). Minimal skin incision (lower left panel). Cosmetic result after 1 week (lower right panel). (B) Pedigree of the proband's family. (C and D) Direct sequencing revealed the splice site mutation c.2025+1G>A within CCM1 likely resulting in skipping of exon 18. (E) A smaller transcript is visible in the proband. (F) Electropherogram showing the junction between exon 17 and exon 19 in the smaller transcript.
