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 Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The c.137C>T (p.T46I) alteration is located in exon 3 (coding exon 2) of the SLC2A11 gene. This alteration results from a C to T substitution at nucleotide position 137, causing the threonine (T) at amino acid position 46 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
