Genes affected

TSSK2 (HGNC:11401): (testis specific serine kinase 2) TSSK2 belongs to a family of serine/threonine kinases highly expressed in testis (Hao et al., 2004 [PubMed 15044604]).[supplied by OMIM, Mar 2008]

TSSK2 links:

ESS2 (HGNC:16817): (ess-2 splicing factor homolog) This gene is located within the minimal DGS critical region (MDGCR) thought to contain the gene(s) responsible for a group of developmental disorders. These disorders include DiGeorge syndrome, velocardiofacial syndrome, conotruncal anomaly face syndrome, and some familial or sporadic conotruncal cardiac defects which have been associated with microdeletion of 22q11.2. The encoded protein may be a component of C complex spliceosomes, and the orthologous protein in the mouse localizes to the nucleus. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Dec 2015]

Ambry Genetics

Dec 12, 2023

The c.98G>A (p.R33H) alteration is located in exon 1 (coding exon 1) of the TSSK2 gene. This alteration results from a G to A substitution at nucleotide position 98, causing the arginine (R) at amino acid position 33 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
