Genes affected

PGBD2 (HGNC:19399): (piggyBac transposable element derived 2) The piggyBac family of proteins, found in diverse animals, are transposases related to the transposase of the canonical piggyBac transposon from the moth, Trichoplusia ni. This family also includes genes in several genomes, including human, that appear to have been derived from the piggyBac transposons. This gene belongs to the subfamily of piggyBac transposable element derived (PGBD) genes. The PGBD proteins appear to be novel, with no obvious relationship to other transposases, or other known protein families. The exact function of this gene is not known. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Ambry Genetics

Dec 14, 2023

The c.733G>C (p.V245L) alteration is located in exon 3 (coding exon 2) of the PGBD2 gene. This alteration results from a G to C substitution at nucleotide position 733, causing the valine (V) at amino acid position 245 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
