Genes affected

LETMD1 (HGNC:24241): (LETM1 domain containing 1) This gene encodes a mitochondrial outer membrane protein. It has a potential role in tumorigenesis, which may result from negative regulation of the p53 tumor suppressor gene. Alternatively spliced transcript variants have been noted for this gene.

Collection Method: clinical testing

The c.17T>C (p.V6A) alteration is located in exon 1 (coding exon 1) of the LETMD1 gene. This alteration results from a T to C substitution at nucleotide position 17, causing the valine (V) at amino acid position 6 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
