Variant summary

Our verdict is Likely benign. The variant received -5 ACMG points: 1P and 6B. PP3BP4BP6BS2

The ENST00000273077.9(PNKD):c.1102C>T(p.Arg368Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000582 in 1,614,004 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 Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R368Q) has been classified as Uncertain significance.

Genes affected

PNKD (HGNC:9153): (PNKD metallo-beta-lactamase domain containing) This gene is thought to play a role in the regulation of myofibrillogenesis. Mutations in this gene have been associated with the movement disorder paroxysmal non-kinesigenic dyskinesia. Alternative splicing results in multiple transcript variants.

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

PP3

Multiple lines of computational evidence support a deleterious effect 8: AlphaMissense, BayesDel_addAF, BayesDel_noAF, Cadd, Dann, M_CAP, REVEL, REVEL [when max_spliceai, FATHMM_MKL, MetaRNN, MutationTaster, phyloP100way_vertebrate was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.3283694).

BP6

Variant 2-218344925-C-T is Benign according to our data. Variant chr2-218344925-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 1149077.

BS2

High AC in GnomAdExome4 at 90 AD gene.
