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]

NGFR-AS1 (HGNC:55555): (NGFR antisense RNA 1)

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

The c.514G>C (p.D172H) alteration is located in exon 3 (coding exon 3) of the NGFR gene. This alteration results from a G to C substitution at nucleotide position 514, causing the aspartic acid (D) at amino acid position 172 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
