Variant summary
Our verdict is Likely benign. Variant got -3 ACMG points: 1P and 4B. PP3BS2
The NM_021098.3(CACNA1H):c.3059C>A(p.Ala1020Glu) variant causes a missense change. The variant allele was found at a frequency of 0.00000434 in 1,612,346 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A1020V) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Feb 09, 2022 | This variant has not been reported in the literature in individuals affected with CACNA1H-related conditions. 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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 529558). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change replaces alanine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 1020 of the CACNA1H protein (p.Ala1020Glu). - |
