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]

The c.312A>T (p.E104D) alteration is located in exon 2 (coding exon 2) of the PHF3 gene. This alteration results from a A to T substitution at nucleotide position 312, causing the glutamic acid (E) at amino acid position 104 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
