Arina Puzriakova (Genomics England Curator)

Comment on list classification: Upgrading to Amber as another patient has been identified with biallelic variants (c.384G>T; c.926T>A) in the MAN2B2 gene, who displayed immune dysregulation as part of the phenotype (PMID: 38622837)

Achchuthan Shanmugasundram (Genomics England Curator)

Red List (low evidence)

Comment on list classification: There is only one case reported with immunodeficiency (PMID:31775018). The patient reported in PMID:35637269 presented with severe developmental delay and dysmorphic facial features as in the previous case, but do not present with immunodeficiency. Hence, this gene can only be rated red with current evidence.
