Genes affected

GEMIN5 (HGNC:20043): (gem nuclear organelle associated protein 5) This gene encodes a WD repeat protein that is a component of the survival of motor neurons (SMN) complex. The SMN complex plays a critical role in mRNA splicing through the assembly of spliceosomal small nuclear ribonucleoproteins (snRNPs), and may also mediate the assembly and transport of other classes of ribonucleoproteins. The encoded protein is the snRNA-binding component of the SMN complex. Dysregulation of this gene may play a role in alternative mRNA splicing and tumor cell motility. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Nov 2011]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.01176995).

BS1

Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00454 (692/152298) while in subpopulation NFE AF= 0.00722 (491/68022). AF 95% confidence interval is 0.00669. There are 2 homozygotes in gnomad4. There are 314 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
