Variant summary

Our verdict is Likely benign. Variant got -1 ACMG points: 4P and 5B. PM2PP3_ModerateBP6BS1

The NM_000069.3(CACNA1S):​c.1382C>T​(p.Thr461Ile) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000477 in 1,614,052 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 Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T461N) has been classified as Uncertain significance.

Genes affected
CACNA1S (HGNC:1397): (calcium voltage-gated channel subunit alpha1 S) This gene encodes one of the five subunits of the slowly inactivating L-type voltage-dependent calcium channel in skeletal muscle cells. Mutations in this gene have been associated with hypokalemic periodic paralysis, thyrotoxic periodic paralysis and malignant hyperthermia susceptibility. [provided by RefSeq, Jul 2008]

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.1382C>T (p.T461I) alteration is located in exon 10 (coding exon 10) of the CACNA1S gene. This alteration results from a C to T substitution at nucleotide position 1382, causing the threonine (T) at amino acid position 461 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
