Description

Observed with a second FANCA variant in unrelated patients with Fanconi anemia in published literature, but it is not known whether the variants occurred on the same (in cis) or on different (in trans) chromosomes (Ameziane 2008, Kimble 2018); Published functional studies demonstrate decreased FANCA levels and impaired ubiquitination and foci formation upon MMC-induced damage; however, functional complementation assays show that overexpresson of this variant exhibited a level of activity similar to WT, suggesting that this may be a hypomorphic variant (Ameziane 2008, Lach 2020); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 29098742, 33172906, 17924555, 33822308)
