Genes affected
IMP4 (HGNC:30856): (IMP U3 small nucleolar ribonucleoprotein 4) The protein encoded by this gene, along with IMP3 and MPP10, is part of the 60-80S U3 small nucleolar ribonucleoprotein (U3 snoRNP) complex. This complex is necessary for the early cleavage steps of pre-18S ribosomal RNA processing. Several transcript variants encoding different isoforms have been found for this gene.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Mar 07, 2024 | The c.116A>G (p.N39S) alteration is located in exon 3 (coding exon 3) of the IMP4 gene. This alteration results from a A to G substitution at nucleotide position 116, causing the asparagine (N) at amino acid position 39 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
