Genes affected

KLHDC3 (HGNC:20704): (kelch domain containing 3) The protein encoded by this gene contains six repeated kelch motifs that are structurally similar to recombination activating gene 2, a protein involved in the activation of the V(D)J recombination. In mouse, this gene is found to be expressed specifically in testis. Its expression in pachytene spermatocytes is localized to cytoplasma and meiotic chromatin, suggesting that this gene may be involved in meiotic recombination. [provided by RefSeq, Jun 2012]

Ambry Genetics

Oct 25, 2023

The c.335C>T (p.T112M) alteration is located in exon 4 (coding exon 3) of the KLHDC3 gene. This alteration results from a C to T substitution at nucleotide position 335, causing the threonine (T) at amino acid position 112 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
