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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 31, 2024The c.363G>T (p.M121I) alteration is located in exon 6 (coding exon 5) of the NMD3 gene. This alteration results from a G to T substitution at nucleotide position 363, causing the methionine (M) at amino acid position 121 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
