Variant summary

Our verdict is Benign. The variant received -8 ACMG points: 8P and 16B. PVS1BP6_Very_StrongBS1BS2

The ENST00000381529.9(CSF2RA):c.728_729insGTCGGTGAGACAGAAAG(p.Tyr243ValfsTer16) variant causes a frameshift, stop gained change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00221 in 1,613,822 control chromosomes in the GnomAD database, including 70 homozygotes. There are 1,603 hemizygotes in GnomAD. It is difficult to determine the true allele frequency of this variant because it is of type INS_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. Variant has been reported in ClinVar as Likely benign (★★). Variant results in nonsense mediated mRNA decay.

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]
