Genes affected
PAFAH1B1 (HGNC:8574): (platelet activating factor acetylhydrolase 1b regulatory subunit 1) This locus was identified as encoding a gene that when mutated or lost caused the lissencephaly associated with Miller-Dieker lissencephaly syndrome. This gene encodes the non-catalytic alpha subunit of the intracellular Ib isoform of platelet-activating factor acteylhydrolase, a heterotrimeric enzyme that specifically catalyzes the removal of the acetyl group at the SN-2 position of platelet-activating factor (identified as 1-O-alkyl-2-acetyl-sn-glyceryl-3-phosphorylcholine). Two other isoforms of intracellular platelet-activating factor acetylhydrolase exist: one composed of multiple subunits, the other, a single subunit. In addition, a single-subunit isoform of this enzyme is found in serum. [provided by RefSeq, Apr 2009]

ACMG classification
Classification made for transcript
Verdict is Likely_pathogenic. Variant got 9 ACMG points.
PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the PAFAH1B1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 39 curated pathogenic missense variants (we use a threshold of 10). The gene has 16 curated benign missense variants. Gene score misZ: 3.5284 (above the threshold of 3.09). Trascript score misZ: 3.7057 (above the threshold of 3.09). GenCC associations: The gene is linked to lissencephaly due to LIS1 mutation.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.939
PP5
Variant 17-2680170-C-G is Pathogenic according to our data. Variant chr17-2680170-C-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 159488.Status of the report is criteria_provided_single_submitter, 1 stars.
