Genes affected

PHF10 (HGNC:18250): (PHD finger protein 10) This gene contains a predicted ORF that encodes a protein with two zinc finger domains. The function of the encoded protein is not known. Sequence analysis suggests that multiple alternatively spliced transcript variants are derived from this gene but the full-length nature of only two of them is known. These two splice variants encode different isoforms. A pseudogene for this gene is located on Xq28. [provided by RefSeq, Jul 2008]

C6orf120 (HGNC:21247): (chromosome 6 open reading frame 120) This gene encodes a conserved, N-glycosylated protein that likely functions in the cellular response to endoplasmic reticulum stress. This protein is able to induce apoptosis in vitro in CD4+ T-cells. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2015]

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=0.28822368).

The c.1483A>C (p.S495R) alteration is located in exon 12 (coding exon 12) of the PHF10 gene. This alteration results from a A to C substitution at nucleotide position 1483, causing the serine (S) at amino acid position 495 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
