Description

The CUBN c.1010C>T; p.Pro337Leu variant (rs202153130) is reported in the literature in multiple individuals affected with a hereditary vitamin B12 deficiency syndrome (Hauck 2008, Tanner 2012). Affected individuals with this variant have each been reported to carry an additional pathogenic variant (Tanner 2012), including one individual with a partial CUBN deletion confirmed in trans to p.Pro337Leu (Hauck 2008). The p.Pro337Leu variant is found in the non-Finnish European population with an overall allele frequency of 0.02% (29/129158 alleles) in the Genome Aggregation Database. The proline at codon 337 is highly conserved and computational analyses (SIFT, PolyPhen-2) predict that this variant is deleterious. Based on available information, this variant is considered to be likely pathogenic. References: Hauck FH et al.
