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 GeneticsNov 01, 2022The c.119G>A (p.C40Y) alteration is located in exon 2 (coding exon 2) of the TYW5 gene. This alteration results from a G to A substitution at nucleotide position 119, causing the cysteine (C) at amino acid position 40 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
