Genes affected
CCDC191 (HGNC:29272): (coiled-coil domain containing 191)
QTRT2 (HGNC:25771): (queuine tRNA-ribosyltransferase accessory subunit 2) This gene encodes a subunit of tRNA-guanine transglycosylase. tRNA-guanine transglycosylase is a heterodimeric enzyme complex that plays a critical role in tRNA modification by synthesizing the 7-deazaguanosine queuosine, which is found in tRNAs that code for asparagine, aspartic acid, histidine, and tyrosine. The encoded protein may play a role in the queuosine 5'-monophosphate salvage pathway. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 13, 2024The c.692T>A (p.V231E) alteration is located in exon 6 (coding exon 6) of the CCDC191 gene. This alteration results from a T to A substitution at nucleotide position 692, causing the valine (V) at amino acid position 231 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
