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 -11 ACMG points.

PM1
In a mutagenesis_site Loss of BRCA2-, FANCD2- and XRCC3-binding. No effect on complex formation with FANCA and FANCF. (size 0) in uniprot entity FANCG_HUMAN
BP4
Computational evidence support a benign effect (MetaRNN=0.0034295917).
BP6
Variant 9-35079505-G-A is Benign according to our data. Variant chr9-35079505-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 134358.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=2, not_provided=1, Benign=3, Uncertain_significance=1}.
BS1
Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.00172 (262/152332) while in subpopulation SAS AF= 0.00995 (48/4824). AF 95% confidence interval is 0.00771. There are 3 homozygotes in gnomad4. There are 146 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
BS2
High Homozygotes in GnomAd4 at 3 AR gene

Fanconi anemia complementation group G Uncertain:1Benign:2
Uncertain significance, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaApr 27, 2017This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -
