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]

Ambry Genetics

Aug 16, 2022

The c.616G>A (p.D206N) alteration is located in exon 8 (coding exon 7) of the PIR gene. This alteration results from a G to A substitution at nucleotide position 616, causing the aspartic acid (D) at amino acid position 206 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
