Genes affected

KLHL10 (HGNC:18829): (kelch like family member 10) The protein encoded by this gene belongs to the kelch repeat-containing family, and contains an N-terminal BTB/POZ domain a BACK domain and six C-terminal kelch repeats. Kelch domains are thought to form a four stranded beta-sheet blade structure that can fold into a beta-propeller domain when multiple kelch repeats are found together. Mutations in this gene have been associated with oligozoospermia in some infertile males. [provided by RefSeq, Jul 2016]

KLHL10 Gene-Disease associations (from GenCC):

• male infertility with azoospermia or oligozoospermia due to single gene mutation

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet
• spermatogenic failure 11

  Inheritance: AD Classification: LIMITED Submitted by: Ambry Genetics

ACMG classification

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.937

Collection Method: clinical testing

The c.422G>C (p.C141S) alteration is located in exon 2 (coding exon 2) of the KLHL10 gene. This alteration results from a G to C substitution at nucleotide position 422, causing the cysteine (C) at amino acid position 141 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
