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]

Jan 17, 2024

The c.535C>G (p.L179V) alteration is located in exon 4 (coding exon 4) of the TMEM26 gene. This alteration results from a C to G substitution at nucleotide position 535, causing the leucine (L) at amino acid position 179 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
