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.238C>T (p.P80S) alteration is located in exon 2 (coding exon 2) of the LETMD1 gene. This alteration results from a C to T substitution at nucleotide position 238, causing the proline (P) at amino acid position 80 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
