Genes affected

TMEM64 (HGNC:25441): (transmembrane protein 64) Predicted to be involved in negative regulation of canonical Wnt signaling pathway; negative regulation of osteoblast differentiation; and positive regulation of fat cell differentiation. Predicted to act upstream of or within several processes, including positive regulation of bone resorption; positive regulation of osteoclast differentiation; and regulation of ATPase activity. Predicted to be located in endoplasmic reticulum. Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

The c.938T>G (p.V313G) alteration is located in exon 2 (coding exon 2) of the TMEM64 gene. This alteration results from a T to G substitution at nucleotide position 938, causing the valine (V) at amino acid position 313 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
