Genes affected

MEIOB (HGNC:28569): (meiosis specific with OB-fold) Predicted to enable chromatin binding activity; single-stranded DNA 3'-5' exodeoxyribonuclease activity; and single-stranded DNA binding activity. Predicted to be involved in double-strand break repair via homologous recombination; fertilization; and meiotic nuclear division. Predicted to be located in cytoplasm. Implicated in spermatogenic failure 22. [provided by Alliance of Genome Resources, Apr 2022]

MEIOB Gene-Disease associations (from GenCC):

• spermatogenic failure 22

  Inheritance: AR Classification: STRONG Submitted by: Labcorp Genetics (formerly Invitae)
• male infertility with azoospermia or oligozoospermia due to single gene mutation

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Likely_benign. The variant received -4 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.03).
