Genes affected

LIN28A (HGNC:15986): (lin-28 homolog A) This gene encodes a LIN-28 family RNA-binding protein that acts as a posttranscriptional regulator of genes involved in developmental timing and self-renewal in embryonic stem cells. The encoded protein functions through direct interaction with target mRNAs and by disrupting the maturation of certain miRNAs involved in embryonic development. This protein prevents the terminal processing of the LET7 family of microRNAs which are major regulators of cellular growth and differentiation. Aberrant expression of this gene is associated with cancer progression in multiple tissues. [provided by RefSeq, Sep 2015]

The c.575G>A (p.R192Q) alteration is located in exon 4 (coding exon 4) of the LIN28A gene. This alteration results from a G to A substitution at nucleotide position 575, causing the arginine (R) at amino acid position 192 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
