Genes affected

PHF24 (HGNC:29180): (PHD finger protein 24) Predicted to enable metal ion binding activity. Predicted to act upstream of or within several processes, including detection of mechanical stimulus involved in sensory perception of pain; gamma-aminobutyric acid signaling pathway; and regulation of GABAergic synaptic transmission. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.038731456).

Collection Method: clinical testing

The c.334G>C (p.D112H) alteration is located in exon 2 (coding exon 1) of the PHF24 gene. This alteration results from a G to C substitution at nucleotide position 334, causing the aspartic acid (D) at amino acid position 112 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
