Genes affected

PABPC1L (HGNC:15797): (poly(A) binding protein cytoplasmic 1 like) This gene belongs to the polyadenylate-binding protein type-1 family of proteins. Members of this family bind to the polyA tails of mRNAs to regulate mRNA stability and translation. The mouse ortholog of this gene is required for female fertility. In human, expression of a functional protein is regulated by alternative splicing. The protein-coding splice variant for this gene is abundantly expressed in human oocytes, while a noncoding splice variant subject to nonsense-mediated decay is the predominant splice variant expressed in somatic tissues.

The c.307A>G (p.I103V) alteration is located in exon 2 (coding exon 2) of the PABPC1L gene. This alteration results from a A to G substitution at nucleotide position 307, causing the isoleucine (I) at amino acid position 103 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
