Missense mutation at the C-terminus of PAX6 negatively modulates homeodomain function
PMID: 11309364
Variant p.Q422R and p.P375Q
Gene: PAX6
Disease: Ocular dysgenesis
InheritancePattern: AD
Notes both p.q422R and p.P375Q had lower transcriptional activation of HD targeted sequences and lost binding to homeobox domain sequences in EMSA assay showing that the AA substitution constituted a loss of function for DNA binding with the homeobox DNA binding domain. Proband was positve for aniridia, foveal hypoplasia and cataracts in a 3yo girl.
