Genes affected

SLC2A11 (HGNC:14239): (solute carrier family 2 member 11) This gene belongs to a family of proteins that mediate the transport of sugars across the cell membrane. The encoded protein transports glucose and fructose. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]

ENSG00000251357 (HGNC:):

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=0.04173076).

The c.577C>G (p.Q193E) alteration is located in exon 7 (coding exon 6) of the SLC2A11 gene. This alteration results from a C to G substitution at nucleotide position 577, causing the glutamine (Q) at amino acid position 193 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
