Cataract Panel
Use
Cataracts are opacities of the lens that block or scatter light and may occur due to protein accumulation or developmental defects. They present congenitally or later and can accompany other ocular abnormalities such as microphtalmia and glaucoma. Genetic testing helps identify causative variants, distinguishes isolated from syndromic forms, informs prognosis, guides surgical and genetic counseling decision-making, and enables carrier testing for family members.

Limitations
Technical sensitivity is estimated >99% for single nucleotide variants. Not reliable for deletions >20 bp, insertions or rearrangements >10 bp, low-level mosaicism. CNV assessment cannot reliably detect variants <500 bp or mosaicism, and cannot identify balanced chromosomal aberrations. Exon-level CNV detection depends on sequence properties of targeted regions.
