Variant summary
Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4_Moderate
The NM_020937.4(FANCM):c.3731A>G(p.Glu1244Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000404 in 1,608,926 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E1244D) has been classified as Uncertain significance.

Spermatogenic failure 28;C4748170:Premature ovarian failure 15 Uncertain:2
FANCM NM_020937.3 exon 14 p.Glu1244Gly (c.3731A>G): This variant has not been reported in the literature but is present in 3/125158 European alleles in the Genome Aggregation Database (http://gnomad.broadinstitute.org/rs746030136). Evolutionary conservation and computational predictive tools for this variant are unclear. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -

Fanconi anemia Uncertain:1
This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 1244 of the FANCM protein (p.Glu1244Gly). This variant is present in population databases (rs746030136, gnomAD 0.008%). This variant has not been reported in the literature in individuals affected with FANCM-related conditions. ClinVar contains an entry for this variant (Variation ID: 566886). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The glycine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
