Variant summary

Our verdict is Likely benign. Variant got -1 ACMG points: 4P and 5B. PM2PM5BP4_StrongBS1_Supporting

The NM_130439.3(MXI1):c.346C>G(p.Arg116Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000065 in 1,614,150 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R116P) has been classified as Likely pathogenic.

Genes affected

MXI1 (HGNC:7534): (MAX interactor 1, dimerization protein) Expression of the c-myc gene, which produces an oncogenic transcription factor, is tightly regulated in normal cells but is frequently deregulated in human cancers. The protein encoded by this gene is a transcriptional repressor thought to negatively regulate MYC function, and is therefore a potential tumor suppressor. This protein inhibits the transcriptional activity of MYC by competing for MAX, another basic helix-loop-helix protein that binds to MYC and is required for its function. Defects in this gene are frequently found in patients with prostate tumors. Three alternatively spliced transcripts encoding different isoforms have been described. Additional alternatively spliced transcripts may exist but the products of these transcripts have not been verified experimentally. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PM5

Other missense variant is known to change same aminoacid residue: Variant chr10-110228261-G-C is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 2445366.We mark this variant Likely_pathogenic, oryginal submissions are: {Likely_pathogenic=1, Uncertain_significance=1}.

BP4

Computational evidence support a benign effect (MetaRNN=0.052536905).

BS1

Variant frequency is greater than expected in population afr. gnomad4_exome allele frequency = 0.0000431 (63/1461872) while in subpopulation AFR AF= 0.00108 (36/33480). AF 95% confidence interval is 0.000798. There are 0 homozygotes in gnomad4_exome. There are 43 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The c.346C>G (p.R116G) alteration is located in exon 2 (coding exon 2) of the MXI1 gene. This alteration results from a C to G substitution at nucleotide position 346, causing the arginine (R) at amino acid position 116 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
