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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 28, 2024The c.320G>T (p.R107I) alteration is located in exon 1 (coding exon 1) of the TMEM64 gene. This alteration results from a G to T substitution at nucleotide position 320, causing the arginine (R) at amino acid position 107 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
