Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The ENST00000315796.5(METAP1D):​c.932C>T​(p.Ser311Leu) variant causes a missense, splice region change. The variant allele was found at a frequency of 0.0000756 in 1,614,070 control chromosomes in the GnomAD database, with no homozygous occurrence. 1/1 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S311A) has been classified as Uncertain significance.

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 GeneticsMay 23, 2024The c.932C>T (p.S311L) alteration is located in exon 10 (coding exon 10) of the METAP1D gene. This alteration results from a C to T substitution at nucleotide position 932, causing the serine (S) at amino acid position 311 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
