Genes affected
PIR (HGNC:30048): (pirin) This gene encodes a member of the cupin superfamily. The encoded protein is an Fe(II)-containing nuclear protein expressed in all tissues of the body and concentrated within dot-like subnuclear structures. Interactions with nuclear factor I/CCAAT box transcription factor as well as B cell lymphoma 3-encoded oncoprotein suggest the encoded protein may act as a transcriptional cofactor and be involved in the regulation of DNA transcription and replication. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jul 2008]

The c.847A>T (p.T283S) alteration is located in exon 10 (coding exon 9) of the PIR gene. This alteration results from a A to T substitution at nucleotide position 847, causing the threonine (T) at amino acid position 283 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
