Variant summary

Our verdict is Benign. Variant got -13 ACMG points: 2P and 15B. PM2BP4_ModerateBP6_Very_StrongBP7BS1

The NM_018297.4(NGLY1):ā€‹c.334A>Cā€‹(p.Arg112=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000626 in 1,614,192 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (ā˜…ā˜…). Synonymous variant affecting the same amino acid position (i.e. R112R) has been classified as Likely benign.

Genes affected
NGLY1 (HGNC:17646): (N-glycanase 1) This gene encodes an enzyme that catalyzes hydrolysis of an N(4)-(acetyl-beta-D-glucosaminyl) asparagine residue to N-acetyl-beta-D-glucosaminylamine and a peptide containing an aspartate residue. The encoded enzyme may play a role in the proteasome-mediated degradation of misfolded glycoproteins. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Feb 2009]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -13 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.45).
BP6
Variant 3-25764224-T-G is Benign according to our data. Variant chr3-25764224-T-G is described in ClinVar as [Likely_benign]. Clinvar id is 474223.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=1.99 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00044 (67/152306) while in subpopulation AFR AF= 0.00135 (56/41556). AF 95% confidence interval is 0.00107. There are 0 homozygotes in gnomad4. There are 31 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
