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 was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.002554506).

BP6

Variant 9-35075025-C-T is Benign according to our data. Variant chr9-35075025-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 134361.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00826 (1258/152300) while in subpopulation NFE AF = 0.0112 (763/68032). AF 95% confidence interval is 0.0106. There are 13 homozygotes in GnomAd4. There are 643 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 13 AR gene
