Genes affected

NMD3 (HGNC:24250): (NMD3 ribosome export adaptor) Ribosomal 40S and 60S subunits associate in the nucleolus and are exported to the cytoplasm. The protein encoded by this gene is involved in the passage of the 60S subunit through the nuclear pore complex and into the cytoplasm. Several transcript variants exist for this gene, but the full-length natures of only two have been described to date. [provided by RefSeq, Feb 2016]

Ambry Genetics

Mar 25, 2024

The c.68C>T (p.P23L) alteration is located in exon 3 (coding exon 2) of the NMD3 gene. This alteration results from a C to T substitution at nucleotide position 68, causing the proline (P) at amino acid position 23 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
