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 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.847

The c.589C>T (p.P197S) alteration is located in exon 6 (coding exon 6) of the DPF3 gene. This alteration results from a C to T substitution at nucleotide position 589, causing the proline (P) at amino acid position 197 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
