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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 20, 2024The c.608C>T (p.P203L) alteration is located in exon 5 (coding exon 5) of the LETMD1 gene. This alteration results from a C to T substitution at nucleotide position 608, causing the proline (P) at amino acid position 203 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
