Genes affected

NGFR (HGNC:7809): (nerve growth factor receptor) Nerve growth factor receptor contains an extracellular domain containing four 40-amino acid repeats with 6 cysteine residues at conserved positions followed by a serine/threonine-rich region, a single transmembrane domain, and a 155-amino acid cytoplasmic domain. The cysteine-rich region contains the nerve growth factor binding domain. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.71C>A (p.S24Y) alteration is located in exon 2 (coding exon 2) of the NGFR gene. This alteration results from a C to A substitution at nucleotide position 71, causing the serine (S) at amino acid position 24 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
