Labcorp Genetics (formerly Invitae), Labcorp	RCV000425270	SCV003273283	pathogenic	not provided	2023-10-05	criteria provided, single submitter	clinical testing	This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 672 of the CDAN1 protein (p.Pro672Leu). This variant is present in population databases (rs120074167, gnomAD 0.01%). This missense change has been observed in individual(s) with congenital dyserythropoietic anemia type I (PMID: 12434312, 31900952, 33401150). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is also known as 2129C>T, Pro671Leu. ClinVar contains an entry for this variant (Variation ID: 3179). 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.

This variant is also reported in ClinVar (Variation ID: 3179). This variant is found predominantly in the non-Finnish European population with an allele frequency of 0.01% (17/121,360 alleles) in the Genome Aggregation Database. Computational analyses predict that this variant is deleterious (REVEL: 0.826). Based on available information, this variant is considered to be likely pathogenic. REFERENCES Dgany O et al.
