Genes affected

TMBIM1 (HGNC:23410): (transmembrane BAX inhibitor motif containing 1) Enables death receptor binding activity. Involved in negative regulation of Fas signaling pathway; negative regulation of extrinsic apoptotic signaling pathway via death domain receptors; and negative regulation of protein localization to plasma membrane. Located in Golgi apparatus; endosome membrane; and lysosomal membrane. [provided by Alliance of Genome Resources, Apr 2022]

TMBIM1 links:

PNKD (HGNC:9153): (PNKD metallo-beta-lactamase domain containing) This gene is thought to play a role in the regulation of myofibrillogenesis. Mutations in this gene have been associated with the movement disorder paroxysmal non-kinesigenic dyskinesia. Alternative splicing results in multiple transcript variants.

Ambry Genetics

May 18, 2022

The c.218A>G (p.Y73C) alteration is located in exon 3 (coding exon 2) of the TMBIM1 gene. This alteration results from a A to G substitution at nucleotide position 218, causing the tyrosine (Y) at amino acid position 73 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
