Genes affected

PABPC1 (HGNC:8554): (poly(A) binding protein cytoplasmic 1) This gene encodes a poly(A) binding protein. The protein shuttles between the nucleus and cytoplasm and binds to the 3' poly(A) tail of eukaryotic messenger RNAs via RNA-recognition motifs. The binding of this protein to poly(A) promotes ribosome recruitment and translation initiation; it is also required for poly(A) shortening which is the first step in mRNA decay. The gene is part of a small gene family including three protein-coding genes and several pseudogenes.[provided by RefSeq, Aug 2010]

Ambry Genetics

Nov 30, 2021

The c.1495G>A (p.A499T) alteration is located in exon 11 (coding exon 11) of the PABPC1 gene. This alteration results from a G to A substitution at nucleotide position 1495, causing the alanine (A) at amino acid position 499 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
