Variant summary: CENPE c.4063A>G (p.Lys1355Glu) results in a conservative amino acid change in the encoded protein sequence. Algorithms developed to predict the effect of missense changes on protein structure and function all suggest that this variant is likely to be tolerated. The variant allele was found at a frequency of 0.00019 in 1613980 control chromosomes in the gnomAD database, including 1 homozygote. This frequency is not significantly higher than estimated for a pathogenic variant in CENPE causing Microcephaly 13, Primary, Autosomal Recessive, allowing no conclusion about variant significance. c.4063A>G has been observed in the compound heterozygous state in two siblings affected with microcephalic primordial dwarfism (Mirzaa_2014). These data indicate that the variant may be associated with disease. At least one publication reports experimental evidence evaluating an impact on protein function, however, does not allow convincing conclusions about the variant effect (Mirzaa_2014). The following publication have been ascertained in the context of this evaluation (PMID: 24748105). ClinVar contains an entry for this variant (Variation ID: 157498). Based on the evidence outlined above, the variant was classified as VUS-possibly pathogenic. -
not provided Uncertain:1
Observed with a variant on the opposite allele (in trans) in a patient with microcephalic primordial dwarfism in the published literature (Mirzaa et al., 2014); In silico analysis supports that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 34426522, 22974711, 24748105) -
