May play a role in the structure and strength of both muscle and bone. Interacts with ATAD3A. Expressed in skeletal muscle, heart, brain but not in bone. Embryonic lethality in homozygotes mice after embryonic day 9.5 (PubMed:29618611). Tamoxifen-inducible Fam210a homozygous knockout mice exhibit decreased grip strength, lean mass of all limbs, bone mineral density, bone biomechanical strength, and elevated osteoclast activity with microarchitectural deterioration of trabecular and cortical bones (PubMed:29618611). Belongs to the FAM210 family.
