Genes affected

TMEM26 (HGNC:28550): (transmembrane protein 26) This gene encodes a protein containing multiple transmembrane helices. It is a selective surface protein marker of brite/beige adipocytes, which may coexist with classical brown adipocytes in brown adipose tissue. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Dec 2015]

Ambry Genetics

Jun 26, 2023

The c.503G>A (p.G168E) alteration is located in exon 4 (coding exon 4) of the TMEM26 gene. This alteration results from a G to A substitution at nucleotide position 503, causing the glycine (G) at amino acid position 168 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
