Functional assessment of a novel COL4A5 splice region variant and immunostaining of plucked hair follicles as an alternative method of diagnosis in X-linked Alport syndrome.

Abstract excerpt

BACKGROUND: Many COL4A5 splice region variants have been described in patients with X-linked Alport syndrome, but few have been confirmed by functional analysis to actually cause defective splicing. We sought to demonstrate that a novel COL4A5 splice region variant in a family with Alport syndrome is pathogenic using functional studies. We also describe an alternative method of diagnosis. METHODS: Targeted...
