NM_021922.3:c.1331T>C
Variant summary
Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2PP3
The NM_021922.3(FANCE):c.1331T>C(p.Leu444Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000291 in 1,613,992 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. L444L) has been classified as Likely benign.

Submissions by phenotype
not specified Uncertain:1
The p.Leu444Pro (NM_021922.2 c.1331T>C) variant in FANCE has not been reported i n the literature. This variant has been identified in 0.001% (1/66670) of Europe an chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinsti tute.org; dbSNP rs745685973). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role for Fanconi anemia. Computational prediction tools and conservation analysis suggest that the p.Leu444Pro variant may impact the protein, though this information is not predictive enough to determine pathogenicity. In summary, the clinical sign ificance of the p.Leu444Pro variant is uncertain. -
Fanconi anemia complementation group E Uncertain:1
This sequence change replaces leucine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 444 of the FANCE protein (p.Leu444Pro). This variant is present in population databases (rs745685973, gnomAD 0.002%). This missense change has been observed in individual(s) with multiple congenital anomalies and hydrocephalus (PMID: 30609409). ClinVar contains an entry for this variant (Variation ID: 517206). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. -
