Genes affected

DPF3 (HGNC:17427): (double PHD fingers 3) This gene encodes a member of the D4 protein family. The encoded protein is a transcription regulator that binds acetylated histones and is a component of the BAF chromatin remodeling complex. Alternate splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2013]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.34279788).

The c.433G>A (p.V145I) alteration is located in exon 5 (coding exon 5) of the DPF3 gene. This alteration results from a G to A substitution at nucleotide position 433, causing the valine (V) at amino acid position 145 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
