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]

Aug 04, 2023

The c.185C>T (p.P62L) alteration is located in exon 1 (coding exon 1) of the TOR1B gene. This alteration results from a C to T substitution at nucleotide position 185, causing the proline (P) at amino acid position 62 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
