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 | Jun 22, 2021 | The c.326C>T (p.P109L) alteration is located in exon 5 (coding exon 5) of the IMP4 gene. This alteration results from a C to T substitution at nucleotide position 326, causing the proline (P) at amino acid position 109 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
