Genes affected

TOR1B (HGNC:11995): (torsin family 1 member B) The protein encoded by this gene is an ATPase found primarily in the endoplasmic reticulum and nuclear envelope. This gene has a highly-similar neighboring gene, TOR1A, that encodes a protein that is likely to interact in a complex with this protein. Finally, this protein may act as a chaperone and play a role in maintaining the integrity of the nuclear envelope and endoplasmic reticulum. Several transcript variants, some protein-coding and others non-protein coding, have been found for this gene. [provided by RefSeq, Dec 2015]

Jun 23, 2023

The c.580C>A (p.L194I) alteration is located in exon 3 (coding exon 3) of the TOR1B gene. This alteration results from a C to A substitution at nucleotide position 580, causing the leucine (L) at amino acid position 194 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
