Variant summary
Our verdict is Benign. Variant got -8 ACMG points: 0P and 8B. BP4_StrongBS2
The NM_021098.3(CACNA1H):c.4929+5G>A variant causes a splice donor 5th base, intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000684 in 1,608,562 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 2/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★★).

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jan 24, 2023 | This variant is present in population databases (no rsID available, gnomAD 0.003%). This sequence change falls in intron 27 of the CACNA1H gene. It does not directly change the encoded amino acid sequence of the CACNA1H protein. It affects a nucleotide within the consensus splice site. 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. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. ClinVar contains an entry for this variant (Variation ID: 460133). - |
