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]

The c.976C>T (p.H326Y) alteration is located in exon 6 (coding exon 6) of the TMEM26 gene. This alteration results from a C to T substitution at nucleotide position 976, causing the histidine (H) at amino acid position 326 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
