Genes affected

RNF39 (HGNC:18064): (ring finger protein 39) This gene lies within the major histocompatibility complex class I region on chromosome 6. Studies of a similar rat protein suggest that this gene encodes a protein that plays a role in an early phase of synaptic plasticity. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.19072223).

The c.158C>A (p.A53E) alteration is located in exon 1 (coding exon 1) of the RNF39 gene. This alteration results from a C to A substitution at nucleotide position 158, causing the alanine (A) at amino acid position 53 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
