Variant summary
Our verdict is Benign. The variant received -7 ACMG points: 0P and 7B. BP4_ModerateBP6BS1
The NM_001382567.1(STIM1):c.1847C>T(p.Ala616Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000421 in 1,614,042 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign 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. A616T) has been classified as Uncertain significance.

Variant summary: STIM1 c.1754C>T (p.Ala585Val) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 8e-05 in 251302 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in STIM1 causing STIM1-Related Disorders (8e-05 vs ND), allowing no conclusion about variant significance. To our knowledge, no occurrence of c.1754C>T in individuals affected with STIM1-Related Disorders and no experimental evidence demonstrating its impact on protein function have been reported. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 and classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance.

STIM1 NM_003156.3 exon 12 p.Ala585Val (c.1754C>T): This variant has not been reported in the literature but is present in 0.03% (13/35436) of Latino alleles in the Genome Aggregation Database (https://gnomad.broadinstitute.org/variant/11-4112724-C-T?dataset=gnomad_r2_1). This variant is present in ClinVar (Variation ID:568147). Evolutionary conservation for this variant are unclear; computational predictive tools suggest that this variant may not impact the protein. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain.
Inborn genetic diseases Uncertain:1
The c.1754C>T (p.A585V) alteration is located in exon 12 (coding exon 12) of the STIM1 gene. This alteration results from a C to T substitution at nucleotide position 1754, causing the alanine (A) at amino acid position 585 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
