Genes affected

TMEM38B (HGNC:25535): (transmembrane protein 38B) This gene encodes an intracellular monovalent cation channel that functions in maintenance of intracellular calcium release. Mutations in this gene may be associated with autosomal recessive osteogenesis. [provided by RefSeq, Oct 2012]

TMEM38B Gene-Disease associations (from GenCC):

• osteogenesis imperfecta type 14

  Inheritance: AR Classification: STRONG Submitted by: Labcorp Genetics (formerly Invitae), PanelApp Australia
• osteogenesis imperfecta type 4

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.65).
