Genes affected

NPFF (HGNC:7901): (neuropeptide FF-amide peptide precursor) This gene encodes a member of the FMRFamide related peptide (FARP) family of neuropeptides. The encoded preproprotein is proteolytically processed to generate multiple amidated peptides. These peptides may play a role in the regulation of heart rate and blood pressure and the modulation of morphine-induced antinociception. Patients with hypertension exhibit decreased expression of the encoded protein. Alternative splicing results in multiple transcript variants, at least one of which encodes an isoform that is proteolytically processed. [provided by RefSeq, Feb 2016]

ATF7-NPFF (HGNC:55073): (ATF7-NPFF readthrough) Predicted to enable DNA binding activity and DNA-binding transcription factor activity. Predicted to be involved in regulation of transcription, DNA-templated. Predicted to be located in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

The c.49G>T (p.D17Y) alteration is located in exon 1 (coding exon 1) of the NPFF gene. This alteration results from a G to T substitution at nucleotide position 49, causing the aspartic acid (D) at amino acid position 17 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
