Variant summary

Our verdict is Benign. Variant got -15 ACMG points: 2P and 17B. PM2 BP4_Strong BP6_Very_Strong BP7 BS1

The NM_000760.4(CSF3R):c.1689C>A(p.Thr563=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000288 in 1,614,246 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★).

Genes affected

CSF3R (HGNC:2439): (colony stimulating factor 3 receptor) The protein encoded by this gene is the receptor for colony stimulating factor 3, a cytokine that controls the production, differentiation, and function of granulocytes. The encoded protein, which is a member of the family of cytokine receptors, may also function in some cell surface adhesion or recognition processes. Alternatively spliced transcript variants have been described. Mutations in this gene are a cause of Kostmann syndrome, also known as severe congenital neutropenia. [provided by RefSeq, Aug 2010]

ACMG classification

Verdict is Benign. Variant got -15 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.52).
• BP6: Variant 1-36468109-G-T is Benign according to our data. Variant chr1-36468109-G-T is described in ClinVar as [Likely_benign]. Clinvar id is 476294.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=1.53 with no splicing effect.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00147 (224/152356) while in subpopulation AFR AF= 0.00491 (204/41584). AF 95% confidence interval is 0.00435. There are 0 homozygotes in gnomad4. There are 100 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
