Variant summary
Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PVS1PM2PP5_Moderate
The NM_000170.3(GLDC):c.1444_1445insG(p.Asp482GlyfsTer10) variant causes a frameshift change. The variant allele was found at a frequency of 0.00000549 in 1,456,588 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Pathogenic (★). Synonymous variant affecting the same amino acid position (i.e. D482D) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Dec 03, 2020 | For these reasons, this variant has been classified as Pathogenic. This variant has been observed in individual(s) with clinical features of glycine encephalopathy (PMID: 16450403). This variant is also known as c.1443insG in the literature. ClinVar contains an entry for this variant (Variation ID: 56045). This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Asp482Glyfs*10) in the GLDC gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in GLDC are known to be pathogenic (PMID: 16601880). - |
