Pontocerebellar hypoplasia type 1A Uncertain:3
This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -
This sequence change replaces lysine, which is basic and polar, with glutamic acid, which is acidic and polar, at codon 301 of the VRK1 protein (p.Lys301Glu). This variant is present in population databases (rs149661915, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with VRK1-related conditions. ClinVar contains an entry for this variant (Variation ID: 315123). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Missense variants in this gene are a common cause of disease and they are underrepresented in the general population; In silico analysis indicates that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -

Inborn genetic diseases Uncertain:1
The c.901A>G (p.K301E) alteration is located in exon 11 (coding exon 10) of the VRK1 gene. This alteration results from a A to G substitution at nucleotide position 901, causing the lysine (K) at amino acid position 301 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
