NM_021922.3:c.274C>T
Variant summary
Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP4_StrongBP6
The NM_021922.3(FANCE):c.274C>T(p.Arg92Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000496 in 1,613,994 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R92Q) has been classified as Uncertain significance.

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -

DNA sequence analysis of the FANCE gene demonstrated a sequence change, c.274C>T, in exon 2 that results in an amino acid change, p.Arg92Trp. This sequence change does not appear to have been previously described in patients with FANCE-related disorders and has been described in the gnomAD database with a frequency of 0.032% in the African sub-population (dbSNP rs375195621). The p.Arg92Trp change affects a poorly conserved amino acid residue located in a domain of the FANCE protein that is not known to be functional. In-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL) provide contradictory results for the p.Arg92Trp substitution. Due to these contrasting evidences and the lack of functional studies, the clinical significance of the p.Arg92Trp change remains unknown at this time. -
