Genes affected

TESK2 (HGNC:11732): (testis associated actin remodelling kinase 2) This gene product is a serine/threonine protein kinase that contains an N-terminal protein kinase domain that is structurally similar to the kinase domains of testis-specific protein kinase-1 and the LIM motif-containing protein kinases (LIMKs). Its overall structure is most related to the former, indicating that it belongs to the TESK subgroup of the LIMK/TESK family of protein kinases. This gene is predominantly expressed in testis and prostate. The developmental expression pattern of the rat gene in testis suggests an important role for this gene in meitoic stages and/or early stages of spermiogenesis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2016]

The c.1676C>T (p.S559L) alteration is located in exon 11 (coding exon 10) of the TESK2 gene. This alteration results from a C to T substitution at nucleotide position 1676, causing the serine (S) at amino acid position 559 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
