Genes affected

KTI12 (HGNC:25160): (KTI12 chromatin associated homolog) Predicted to enable ATP binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II and tRNA wobble uridine modification. [provided by Alliance of Genome Resources, Apr 2022]

KTI12 links:

TXNDC12 (HGNC:24626): (thioredoxin domain containing 12) This gene encodes a member of the thioredoxin superfamily. Members of this family are characterized by a conserved active motif called the thioredoxin fold that catalyzes disulfide bond formation and isomerization. This protein localizes to the endoplasmic reticulum and has a single atypical active motif. The encoded protein is mainly involved in catalyzing native disulfide bond formation and displays activity similar to protein-disulfide isomerases. This protein may play a role in defense against endoplasmic reticulum stress. Alternate splicing results in both coding and non-coding variants. [provided by RefSeq, Mar 2012]

The c.680G>A (p.R227Q) alteration is located in exon 1 (coding exon 1) of the KTI12 gene. This alteration results from a G to A substitution at nucleotide position 680, causing the arginine (R) at amino acid position 227 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
