Genes affected
JAGN1 (HGNC:26926): (jagunal homolog 1) The protein encoded by this gene is a transmembrane protein. It functions in the early secretory pathway and is necessary for neutrophil differentiation and survival. Mutations in this gene result in severe congenital neutropenia.

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PVS1
Start lost variant, no new inframe start found.
PS1
Another start lost variant in NM_032492.4 (JAGN1) was described as [Conflicting_classifications_of_pathogenicity] in ClinVar as 156113
BS1
Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00251 (383/152316) while in subpopulation NFE AF= 0.00104 (71/68016). AF 95% confidence interval is 0.000848. There are 8 homozygotes in gnomad4. There are 281 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High Homozygotes in GnomAd4 at 8 AR gene
