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

Dec 17, 2023

The c.494T>C (p.I165T) alteration is located in exon 4 (coding exon 4) of the TMEM26 gene. This alteration results from a T to C substitution at nucleotide position 494, causing the isoleucine (I) at amino acid position 165 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
