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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 24, 2023The c.128G>A (p.R43Q) alteration is located in exon 2 (coding exon 2) of the METAP1D gene. This alteration results from a G to A substitution at nucleotide position 128, causing the arginine (R) at amino acid position 43 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
