Variant 1-161589570-C-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The ENST00000466542.6(FCGR2C):c.142C>A(p.Pro48Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000209 in 143,458 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 8/9 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P48L) has been classified as Uncertain significance.

Genes affected

FCGR2C (HGNC:15626): (Fc gamma receptor IIc (gene/pseudogene)) This gene encodes one of three members of a family of low-affinity immunoglobulin gamma Fc receptors found on the surface of many immune response cells. The encoded protein is a transmembrane glycoprotein and may be involved in phagocytosis and clearing of immune complexes. An allelic polymorphism in this gene results in both coding and non-coding variants. [provided by RefSeq, Apr 2012]

The c.142C>A (p.P48T) alteration is located in exon 3 (coding exon 3) of the FCGR2C gene. This alteration results from a C to A substitution at nucleotide position 142, causing the proline (P) at amino acid position 48 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
