Variant summary

Our verdict is Likely benign. Variant got -6 ACMG points: 0P and 6B. BP4BP6BS2

The NM_172245.4(CSF2RA):c.530G>C(p.Gly177Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000146 in 1,613,188 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 117 hemizygotes in GnomAD. In-silico tool predicts a benign outcome for this variant. 11/18 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another nucleotide change resulting in same amino acid change has been previously reported as Likely benignin ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G177E) has been classified as Uncertain significance.

Genes affected

CSF2RA (HGNC:2435): (colony stimulating factor 2 receptor subunit alpha) The protein encoded by this gene is the alpha subunit of the heterodimeric receptor for colony stimulating factor 2, a cytokine which controls the production, differentiation, and function of granulocytes and macrophages. The encoded protein is a member of the cytokine family of receptors. This gene is found in the pseudoautosomal region (PAR) of the X and Y chromosomes. Multiple transcript variants encoding different isoforms have been found for this gene, with some of the isoforms being membrane-bound and others being soluble. [provided by RefSeq, Jul 2008]

This sequence change replaces glycine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 177 of the CSF2RA protein (p.Gly177Ala). This variant is present in population databases (no rsID available, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with CSF2RA-related conditions. ClinVar contains an entry for this variant (Variation ID: 643235). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on CSF2RA protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
