Genes affected
TYW5 (HGNC:26754): (tRNA-yW synthesizing protein 5) Enables several functions, including iron ion binding activity; protein homodimerization activity; and tRNAPhe (7-(3-amino-3-carboxypropyl)wyosine37-C2)-hydroxylase activity. Involved in wybutosine biosynthetic process. Predicted to be located in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]
C2orf69 (HGNC:26799): (chromosome 2 open reading frame 69) Involved in oxidative phosphorylation. Located in mitochondrion. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 22, 2023The c.896G>A (p.R299Q) alteration is located in exon 8 (coding exon 8) of the TYW5 gene. This alteration results from a G to A substitution at nucleotide position 896, causing the arginine (R) at amino acid position 299 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
