Genes affected
FANCG (HGNC:3588): (FA complementation group G) The Fanconi anemia complementation group (FANC) currently includes FANCA, FANCB, FANCC, FANCD1 (also called BRCA2), FANCD2, FANCE, FANCF, FANCG, FANCI, FANCJ (also called BRIP1), FANCL, FANCM and FANCN (also called PALB2). The previously defined group FANCH is the same as FANCA. Fanconi anemia is a genetically heterogeneous recessive disorder characterized by cytogenetic instability, hypersensitivity to DNA crosslinking agents, increased chromosomal breakage, and defective DNA repair. The members of the Fanconi anemia complementation group do not share sequence similarity; they are related by their assembly into a common nuclear protein complex. This gene encodes the protein for complementation group G. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (MetaRNN=0.012988955).
BP6
Variant 9-35076767-C-T is Benign according to our data. Variant chr9-35076767-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 239969.We mark this variant Likely_benign, oryginal submissions are: {Benign=1, Uncertain_significance=2}.
BS1
Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.000118 (18/152174) while in subpopulation EAS AF= 0.0025 (13/5192). AF 95% confidence interval is 0.00148. There are 0 homozygotes in gnomad4. There are 12 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
