Genes affected
FANCM (HGNC:23168): (FA complementation group M) 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 M. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2015]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -20 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.002779305).
BP6
Variant 14-45196487-C-T is Benign according to our data. Variant chr14-45196487-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 210991.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr14-45196487-C-T is described in Lovd as [Benign].
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00814 (1239/152226) while in subpopulation AFR AF= 0.0283 (1174/41542). AF 95% confidence interval is 0.0269. There are 15 homozygotes in gnomad4. There are 554 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High Homozygotes in GnomAd4 at 15 AR gene
