Genes affected

NPAT (HGNC:7896): (nuclear protein, coactivator of histone transcription) Enables protein C-terminus binding activity; transcription coactivator activity; and transcription corepressor activity. Involved in positive regulation of transcription by RNA polymerase II and regulation of transcription involved in G1/S transition of mitotic cell cycle. Located in Cajal body; Gemini of coiled bodies; and cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method:clinical testing

The p.P1411T variant (also known as c.4231C>A), located in coding exon 18 of the NPAT gene, results from a C to A substitution at nucleotide position 4231. The proline at codon 1411 is replaced by threonine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
