Genes affected

PLAG1 (HGNC:9045): (PLAG1 zinc finger) Pleomorphic adenoma gene 1 encodes a zinc finger protein with 2 putative nuclear localization signals. PLAG1, which is developmentally regulated, has been shown to be consistently rearranged in pleomorphic adenomas of the salivary glands. PLAG1 is activated by the reciprocal chromosomal translocations involving 8q12 in a subset of salivary gland pleomorphic adenomas. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The c.1261T>G (p.L421V) alteration is located in exon 5 (coding exon 2) of the PLAG1 gene. This alteration results from a T to G substitution at nucleotide position 1261, causing the leucine (L) at amino acid position 421 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
