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]

ACMG classification

Verdict is Likely_benign. Variant got -3 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.31).
• BP6: Variant 6-63646802-C-A is Benign according to our data. Variant chr6-63646802-C-A is described in ClinVar as [Likely_benign]. Clinvar id is 3045235.Status of the report is no_assertion_criteria_provided, 0 stars.
