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

Verdict is Pathogenic. Variant got 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 9-85588359-G-A is Pathogenic according to our data. Variant chr9-85588359-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 599381.Status of the report is no_assertion_criteria_provided, 0 stars.
