Genes affected

PGBD1 (HGNC:19398): (piggyBac transposable element derived 1) 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. This gene product is specifically expressed in the brain, however, its exact function is not known. Alternative splicing results in multiple transcript variants encoding the same protein.[provided by RefSeq, May 2010]

The c.587A>G (p.E196G) alteration is located in exon 4 (coding exon 3) of the PGBD1 gene. This alteration results from a A to G substitution at nucleotide position 587, causing the glutamic acid (E) at amino acid position 196 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
