Variant summary
Our verdict is Likely benign. The variant received -4 ACMG points: 1P and 5B. PP3BP6BS1
The NM_000540.3(RYR1):c.14646G>A(p.Thr4882Thr) variant causes a splice region, synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000088 in 1,614,006 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 predicting alterations to normal splicing. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars).

RYR1-related disorder Uncertain:1
This sequence change affects codon 4882 of the RYR1 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the RYR1 protein. This variant also falls at the last nucleotide of exon 101, which is part of the consensus splice site for this exon. This variant is present in population databases (rs536148030, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with RYR1-related conditions. ClinVar contains an entry for this variant (Variation ID: 212095). 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 may create or strengthen a splice site. 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. -
