Genes affected

FNDC5 (HGNC:20240): (fibronectin type III domain containing 5) This gene encodes a secreted protein that is released from muscle cells during exercise. The encoded protein may participate in the development of brown fat. Translation of the precursor protein initiates at a non-AUG start codon at a position that is conserved as an AUG start codon in other organisms. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2013]

Collection Method: clinical testing

The c.448C>T (p.L150F) alteration is located in exon 5 (coding exon 3) of the FNDC5 gene. This alteration results from a C to T substitution at nucleotide position 448, causing the leucine (L) at amino acid position 150 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
