Table 1. Known mutations in CRYBB1 in association with isolated congenital cataract.

Inheritance Phenotype Mutation: protein-level Exon Reference
Autosomal dominant bilateral, pulverulent, affected fetal nucleus,
cortex and anterior and posterior Y-suture region
G220X
→ truncated βB1-crystallin
→ partial loss of 4. Greek-key motif
6 [13]
Autosomal dominant dense nuclear with cortical riders and anterior and
posterior polar opacities and microcornea
X253R
→ elongation of COOH-terminus
→ disruption of β-crystallin interactions
6 [4]
Autosomal dominant bilateral nuclear cataract S228P
→ disturb consecutive β-sheet and make a β-turn
6 [14]
Autosomal dominant bilateral, disc-like opacities in central nucleus region Q223X
→ truncated βB1-crystallin
→ partial loss of 4. Greek-key motif
6 [15]
Autosomal recessive bilateral confluent nuclear opacification N58Tfs106
→ abrogates protein very near to NH2-terminus
2 [16]
Autosomal recessive bilateral, mild nuclear pulverulent cataract M1K
→ abrogates initiation codon
