Genes affected

GDPGP1 (HGNC:34360): (GDP-D-glucose phosphorylase 1) Enables GDP-D-glucose phosphorylase activity. Involved in glucose metabolic process. Predicted to be active in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ENSG00000284626 (HGNC:):

CIB1 (HGNC:16920): (calcium and integrin binding 1) This gene encodes a member of the EF-hand domain-containing calcium-binding superfamily. The encoded protein interacts with many other proteins, including the platelet integrin alpha-IIb-beta-3, DNA-dependent protein kinase, presenilin-2, focal adhesion kinase, p21 activated kinase, and protein kinase D. The encoded protein may be involved in cell survival and proliferation, and is associated with several disease states including cancer and Alzheimer's disease. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2013]

CIB1 Gene-Disease associations (from GenCC):

• epidermodysplasia verruciformis, susceptibility to, 3

  Inheritance: AR Classification: DEFINITIVE, STRONG Submitted by: Labcorp Genetics (formerly Invitae), G2P, Genomics England PanelApp
• epidermodysplasia verruciformis

  Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.1295943).
