Genes affected

PHF3 (HGNC:8921): (PHD finger protein 3) This gene encodes a member of a PHD finger-containing gene family. This gene may function as a transcription factor and may be involved in glioblastomas development. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2014]

Collection Method:clinical testing

The c.413T>C (p.V138A) alteration is located in exon 3 (coding exon 3) of the PHF3 gene. This alteration results from a T to C substitution at nucleotide position 413, causing the valine (V) at amino acid position 138 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
