Variant summary

Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PM1PM2_SupportingPM5PP2PP3_StrongPP5_Moderate

The NM_001127222.2(CACNA1A):c.4043G>C(p.Arg1348Pro) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD Genomes project. In-silico tool predicts a pathogenic outcome for this variant. 12/20 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1348Q) has been classified as Likely pathogenic.

PM1
?
In a hotspot region, there are 8 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 2 uncertain in NM_001127222.2
PM2
?
Very rare variant; Number of alleles below threshold, Median coverage is 32.
PM5
?
Other missense variant is known to change same aminoacid residue: Variant chr19-13262780-C-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 380972. Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
PP2
?
Missense variant where missense usually causes diseases, CACNA1A
PP3
?
MetaRNN computational evidence supports a deleterious effect, 0.975
PP5
?
Variant 19-13262780-C-G is Pathogenic according to our data. Variant chr19-13262780-C-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 1335952. Status of the report is criteria_provided_single_submitter, 1 stars.
