Genes affected

AGTPBP1 (HGNC:17258): (ATP/GTP binding carboxypeptidase 1) NNA1 is a zinc carboxypeptidase that contains nuclear localization signals and an ATP/GTP-binding motif that was initially cloned from regenerating spinal cord neurons of the mouse.[supplied by OMIM, Jul 2002]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 0 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.28197408).

BS1

Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.0000302 (44/1458464) while in subpopulation MID AF= 0.000521 (3/5754). AF 95% confidence interval is 0.000142. There are 0 homozygotes in gnomad4_exome. There are 21 alleles in male gnomad4_exome subpopulation. Median coverage is 30. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Variant summary: AGTPBP1 c.3407G>A (p.Arg1136His) results in a non-conservative amino acid change located in the Peptidase M14-like domain (IPR033852) of the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 4e-05 in 248626 control chromosomes, predominantly at a frequency of 8.8e-05 within the Non-Finnish European subpopulation in the gnomAD database. This frequency is not significantly higher than estimated for a pathogenic variant in AGTPBP1 causing Neurodegeneration, Childhood-Onset, With Cerebellar Atrophy, allowing no conclusion about variant significance. To our knowledge, no occurrence of c.3407G>A in individuals affected with Neurodegeneration, Childhood-Onset, With Cerebellar Atrophy and no experimental evidence demonstrating its impact on protein function have been reported. No submitters have cited clinical-significance assessments for this variant to ClinVar. Based on the evidence outlined above, the variant was classified as uncertain significance. -
