Genes affected
PCMT1 (HGNC:8728): (protein-L-isoaspartate (D-aspartate) O-methyltransferase) This gene encodes a member of the type II class of protein carboxyl methyltransferase enzymes. The encoded enzyme plays a role in protein repair by recognizing and converting D-aspartyl and L-isoaspartyl residues resulting from spontaneous deamidation back to the normal L-aspartyl form. The encoded protein may play a protective role in the pathogenesis of Alzheimer's disease, and single nucleotide polymorphisms in this gene have been associated with spina bifida and premature ovarian failure. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Oct 2011]

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Oct 27, 2021 | The c.34G>T (p.D12Y) alteration is located in exon 1 (coding exon 1) of the PCMT1 gene. This alteration results from a G to T substitution at nucleotide position 34, causing the aspartic acid (D) at amino acid position 12 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
