Genes affected

SLC2A4RG (HGNC:15930): (SLC2A4 regulator) The protein encoded by this gene is a nuclear transcription factor involved in the activation of the solute carrier family 2 member 4 gene. The encoded protein interacts with another transcription factor, myocyte enhancer factor 2, to activate transcription of this gene. [provided by RefSeq, Jul 2008]

SLC2A4RG (HGNC:):

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=0.1183691).

The c.287C>A (p.T96N) alteration is located in exon 3 (coding exon 3) of the SLC2A4RG gene. This alteration results from a C to A substitution at nucleotide position 287, causing the threonine (T) at amino acid position 96 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
