Genes affected

TSPYL5 (HGNC:29367): (TSPY like 5) Predicted to enable chromatin binding activity and histone binding activity. Involved in several processes, including cellular response to gamma radiation; positive regulation of protein kinase B signaling; and positive regulation of protein ubiquitination. Predicted to be active in chromatin and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

The c.741T>G (p.N247K) alteration is located in exon 1 (coding exon 1) of the TSPYL5 gene. This alteration results from a T to G substitution at nucleotide position 741, causing the asparagine (N) at amino acid position 247 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
