Genes affected

TECR (HGNC:4551): (trans-2,3-enoyl-CoA reductase) This gene encodes a multi-pass membrane protein that resides in the endoplasmic reticulum, and belongs to the steroid 5-alpha reductase family. The elongation of microsomal long and very long chain fatty acid consists of 4 sequential reactions. This protein catalyzes the final step, reducing trans-2,3-enoyl-CoA to saturated acyl-CoA. Alternatively spliced transcript variants have been found for this gene.[provided by RefSeq, Apr 2011]

Ambry Genetics

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.262G>T (p.V88L) alteration is located in exon 5 (coding exon 5) of the TECR gene. This alteration results from a G to T substitution at nucleotide position 262, causing the valine (V) at amino acid position 88 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
