As reviewed by Alexandra Njegic, PMID:37978175 reported a cohort of 114 probands with radiographically confirmed vein of Galen malformations (VOGMs), which is the most common and most severe of congenital brain arteriovenous malformations. This includes 55 cases already reported in PMID:30578106. Of these cases, only two were identified with variants in KEL gene (p.(Gln321Ter) & p.(Gly202Ser)).There is no functional evidence available. Hence, this gene should be rated amber with current evidence.
