Genes affected

FASTKD5 (HGNC:25790): (FAST kinase domains 5) Enables rRNA binding activity. Involved in mitochondrial RNA processing. Located in mitochondrial nucleoid and ribonucleoprotein granule. [provided by Alliance of Genome Resources, Apr 2022]

FASTKD5 links:

UBOX5 (HGNC:17777): (U-box domain containing 5) This gene encodes a U-box domain containing protein. The encoded protein interacts with E2 enzymes and may play a role in the ubiquitination pathway. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Jun 2012]

The c.1553A>G (p.D518G) alteration is located in exon 2 (coding exon 1) of the FASTKD5 gene. This alteration results from a A to G substitution at nucleotide position 1553, causing the aspartic acid (D) at amino acid position 518 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
