In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: not found (cov: 32)
• Consequence: SGTB NM_019072.3 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.515

Genes affected

SGTB (HGNC:23567): (small glutamine rich tetratricopeptide repeat co-chaperone beta) Predicted to enable molecular adaptor activity. Predicted to be involved in positive regulation of chaperone-mediated protein folding; posttranslational protein targeting to endoplasmic reticulum membrane; and ubiquitin-dependent ERAD pathway. Predicted to be part of TRC complex. Predicted to be active in membrane. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
