Genes affected

TESK1 (HGNC:11731): (testis associated actin remodelling kinase 1) This gene product is a serine/threonine protein kinase that contains an N-terminal protein kinase domain and a C-terminal proline-rich domain. Its protein kinase domain is most closely related to those of the LIM motif-containing protein kinases (LIMKs). The encoded protein can phosphorylate myelin basic protein and histone in vitro. The testicular germ cell-specific expression and developmental pattern of expression of the mouse gene suggests that this gene plays an important role at and after the meiotic phase of spermatogenesis. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Dec 2015]

The c.896G>A (p.S299N) alteration is located in exon 9 (coding exon 9) of the TESK1 gene. This alteration results from a G to A substitution at nucleotide position 896, causing the serine (S) at amino acid position 299 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
