Genes affected
PITX3 (HGNC:9006): (paired like homeodomain 3) This gene encodes a member of the RIEG/PITX homeobox family, which is in the bicoid class of homeodomain proteins. Members of this family act as transcription factors. This protein is involved in lens formation during eye development. Mutations of this gene have been associated with anterior segment mesenchymal dysgenesis and congenital cataracts. [provided by RefSeq, Jul 2008]
GBF1 (HGNC:4181): (golgi brefeldin A resistant guanine nucleotide exchange factor 1) This gene encodes a member of the Sec7 domain family. The encoded protein is a guanine nucleotide exchange factor that regulates the recruitment of proteins to membranes by mediating GDP to GTP exchange. The encoded protein is localized to the Golgi apparatus and plays a role in vesicular trafficking by activating ADP ribosylation factor 1. The encoded protein has also been identified as an important host factor for viral replication. Multiple transcript variants have been observed for this gene. [provided by RefSeq, Dec 2010]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -4 ACMG points.

PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 1 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 1.4984 (below the threshold of 3.09). Trascript score misZ: 0.65179 (below the threshold of 3.09). GenCC associations: The gene is linked to cataract 11 multiple types, cataract-glaucoma syndrome, early-onset posterior polar cataract, anterior segment dysgenesis 1.
BP4
Computational evidence support a benign effect (MetaRNN=0.29890922).
BS2
High AC in GnomAdExome4 at 10 AD gene.
