Genes affected

PNKP (HGNC:9154): (polynucleotide kinase 3'-phosphatase) This locus represents a gene involved in DNA repair. In response to ionizing radiation or oxidative damage, the protein encoded by this locus catalyzes 5' phosphorylation and 3' dephosphorylation of nucleic acids. Mutations at this locus have been associated with microcephaly, seizures, and developmental delay.[provided by RefSeq, Sep 2010]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -14 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.8).

BP6

Variant 19-49864191-G-A is Benign according to our data. Variant chr19-49864191-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 211921.

BP7

Synonymous conserved (PhyloP=-5.1 with no splicing effect.

BS1

Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.000178 (260/1461832) while in subpopulation SAS AF = 0.00255 (220/86256). AF 95% confidence interval is 0.00227. There are 4 homozygotes in GnomAdExome4. There are 191 alleles in the male GnomAdExome4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 4 AR,AD gene
