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]

The c.844G>T (p.V282L) alteration is located in exon 4 (coding exon 3) of the PITX3 gene. This alteration results from a G to T substitution at nucleotide position 844, causing the valine (V) at amino acid position 282 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
