Genes affected
PROX1 (HGNC:9459): (prospero homeobox 1) The protein encoded by this gene is a member of the homeobox transcription factor family. Members of this family contain a homeobox domain that consists of a 60-amino acid helix-turn-helix structure that binds DNA and RNA. The protein encoded by this gene is conserved across vertebrates and may play an essential role during development. Altered levels of this protein have been reported in cancers of different organs, such as colon, brain, blood, breast, pancreas, liver and esophagus. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2012]

The c.584C>T (p.P195L) alteration is located in exon 2 (coding exon 1) of the PROX1 gene. This alteration results from a C to T substitution at nucleotide position 584, causing the proline (P) at amino acid position 195 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
