Variant summary

Our verdict is Likely pathogenic. The variant received 6 ACMG points: 6P and 0B. PM2 PP3_Strong

The NM_003837.4(FBP2):​c.830G>C​(p.Arg277Pro) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R277L) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 32)
• Consequence: FBP2 NM_003837.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 7.40
• Publications: 3 publications found

Genes affected

FBP2 (HGNC:3607): (fructose-bisphosphatase 2) This gene encodes a gluconeogenesis regulatory enzyme which catalyzes the hydrolysis of fructose 1,6-bisphosphate to fructose 6-phosphate and inorganic phosphate. [provided by RefSeq, Jul 2008]

PCAT7 (HGNC:48824): (prostate cancer associated transcript 7)

ACMG classification

Our verdict: Likely_pathogenic. The variant received 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.987
