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 GeneticsMay 26, 2024The c.833A>G (p.Y278C) alteration is located in exon 6 (coding exon 6) of the TMEM26 gene. This alteration results from a A to G substitution at nucleotide position 833, causing the tyrosine (Y) at amino acid position 278 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
