Genes affected

METAP1D (HGNC:32583): (methionyl aminopeptidase type 1D, mitochondrial) The N-terminal methionine excision pathway is an essential process in which the N-terminal methionine is removed from many proteins, thus facilitating subsequent protein modification. In mitochondria, enzymes that catalyze this reaction are celled methionine aminopeptidases (MetAps, or MAPs; EC 3.4.11.18) (Serero et al., 2003 [PubMed 14532271]).[supplied by OMIM, Mar 2008]

The c.224C>T (p.T75M) alteration is located in exon 3 (coding exon 3) of the METAP1D gene. This alteration results from a C to T substitution at nucleotide position 224, causing the threonine (T) at amino acid position 75 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
