Genes affected

MYO5B (HGNC:7603): (myosin VB) The protein encoded by this gene, together with other proteins, may be involved in plasma membrane recycling. Mutations in this gene are associated with microvillous inclusion disease. [provided by RefSeq, Sep 2009]

MYO5B Gene-Disease associations (from GenCC):

• microvillus inclusion disease

  Inheritance: AR Classification: DEFINITIVE, STRONG, SUPPORTIVE Submitted by: Orphanet, G2P, PanelApp Australia, Labcorp Genetics (formerly Invitae)
• cholestasis, progressive familial intrahepatic, 10

  Inheritance: AR Classification: STRONG Submitted by: Labcorp Genetics (formerly Invitae)
• progressive familial intrahepatic cholestasis type 1

  Inheritance: AR 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=-0.92).
