Genes affected

TREH (HGNC:12266): (trehalase) This gene encodes an enzyme that hydrolyses trehalose, a disaccharide formed from two glucose molecules found mainly in fungi, plants, and insects. A partial duplication of this gene is located adjacent to this locus on chromosome 11. Two transcript variants encoding different isoforms have been found for this gene.

Ambry Genetics

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1524G>T (p.Q508H) alteration is located in exon 13 (coding exon 13) of the TREH gene. This alteration results from a G to T substitution at nucleotide position 1524, causing the glutamine (Q) at amino acid position 508 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

PreventionGenetics, part of Exact Sciences

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The TREH c.1524G>T variant is predicted to result in the amino acid substitution p.Gln508His. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.097% of alleles in individuals of European (Non-Finnish) descent in gnomAD. Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
