Genes affected

CDAN1 (HGNC:1713): (codanin 1) This gene encodes a protein that appears to play a role in nuclear envelope integrity, possibly related to microtubule attachments. Mutations in this gene cause congenital dyserythropoietic anemia type I, a disease resulting in morphological and functional abnormalities of erythropoiesis. [provided by RefSeq, Jul 2009]

Collection Method:clinical testing

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 1130 of the CDAN1 protein (p.Pro1130Leu). This variant is present in population databases (rs80338699, gnomAD 0.006%). This missense change has been observed in individual(s) with clinical features of congenital dyserythropoietic anemia (PMID: 28102861, 29031773, 29676459, 29936674, 33401150). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 3177). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. For these reasons, this variant has been classified as Pathogenic.
