Genes affected

MRTO4 (HGNC:18477): (MRT4 homolog, ribosome maturation factor) This gene encodes a protein sharing a low level of sequence similarity with ribosomal protein P0. While the precise function of the encoded protein is currently unknown, it appears to be involved in mRNA turnover and ribosome assembly. [provided by RefSeq, Jul 2008]

The c.175G>A (p.A59T) alteration is located in exon 3 (coding exon 3) of the MRTO4 gene. This alteration results from a G to A substitution at nucleotide position 175, causing the alanine (A) at amino acid position 59 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
