This variant is located 1 base from the natural splicing region of this exon and consequently can impact intron removal and protein formation. As for the ophthalmological findings, the presence of low visual acuity, high axial myopia, and pathological vitreous gel with a \u201cbeaded\u201d appearance was observed in the index case.
