Genes affected

FAM83G (HGNC:32554): (family with sequence similarity 83 member G) Predicted to enable protein kinase binding activity. Involved in BMP signaling pathway. Located in cytosol and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

FAM83G links:

SLC5A10 (HGNC:23155): (solute carrier family 5 member 10) This gene is a member of the sodium/glucose transporter family. Members of this family are sodium-dependent transporters and can be divided into two subfamilies based on sequence homology, one that co-transports sugars and the second that transports molecules such as ascorbate, choline, iodide, lipoate, monocaroboxylates, and pantothenate. The protein encoded by this gene has the highest affinity for mannose and has been reported to be most highly expressed in the kidney. This protein may function as a kidney-specific, sodium-dependent mannose and fructose co-transporter. Alternative splicing results in multiple transcript variants that encode different protein isoforms. [provided by RefSeq, Jul 2012]

The c.2303G>A (p.R768H) alteration is located in exon 6 (coding exon 5) of the FAM83G gene. This alteration results from a G to A substitution at nucleotide position 2303, causing the arginine (R) at amino acid position 768 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
