Genes affected

DNAJB13 (HGNC:30718): (DnaJ heat shock protein family (Hsp40) member B13) This gene encodes a member of the heat shock protein 40 co-chaperone family which is produced in large amounts in the testis and is located on the radial spokes of the axoneme in human sperm flagella and other flagellar structures. The encoded protein associates with the sperm annulus, as part of the septin complex, through direct interaction with septin 4, during sperm terminal differentiation. Naturally occurring mutations in this gene are associated with primary ciliary dyskinesia and male infertility. [provided by RefSeq, Apr 2017]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.
