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]

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]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.269G>A (p.G90D) alteration is located in exon 4 (coding exon 1) of the GDPGP1 gene. This alteration results from a G to A substitution at nucleotide position 269, causing the glycine (G) at amino acid position 90 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
