Genes affected
NOP58 (HGNC:29926): (NOP58 ribonucleoprotein) The protein encoded by this gene is a core component of box C/D small nucleolar ribonucleoproteins. Some box C/D small nucleolar RNAs (snoRNAs), such as U3, U8, and U14, are dependent upon the encoded protein for their synthesis. This protein is SUMOylated, which is necessary for high affinity binding to snoRNAs. [provided by RefSeq, Nov 2015]

The c.841G>A (p.A281T) alteration is located in exon 9 (coding exon 9) of the NOP58 gene. This alteration results from a G to A substitution at nucleotide position 841, causing the alanine (A) at amino acid position 281 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
