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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 03, 2024The c.772G>A (p.G258R) alteration is located in exon 6 (coding exon 6) of the TMEM26 gene. This alteration results from a G to A substitution at nucleotide position 772, causing the glycine (G) at amino acid position 258 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
