Genes affected

ZPR1 (HGNC:13051): (ZPR1 zinc finger) The protein encoded by this gene is found in the cytoplasm of quiescent cells but translocates to the nucleolus in proliferating cells. The encoded protein interacts with survival motor neuron protein (SMN1) to enhance pre-mRNA splicing and to induce neuronal differentiation and axonal growth. Defects in this gene or the SMN1 gene can cause spinal muscular atrophy. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2015]

The c.1261G>C (p.E421Q) alteration is located in exon 14 (coding exon 14) of the ZPR1 gene. This alteration results from a G to C substitution at nucleotide position 1261, causing the glutamic acid (E) at amino acid position 421 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
