Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_000135.4(FANCA):c.1100G>A(p.Ser367Asn) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000149 in 1,614,112 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. S367S) has been classified as Likely benign.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Aug 27, 2021 | This sequence change replaces serine with asparagine at codon 367 of the FANCA protein (p.Ser367Asn). The serine residue is moderately conserved and there is a small physicochemical difference between serine and asparagine. This variant is present in population databases (rs764286584, ExAC 0.001%). This variant has not been reported in the literature in individuals affected with FANCA-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The asparagine 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. - |
