Null variant observed in compound heterozygosity with another pathogenic variant in a male affected by Bone marrow failure syndrome 3. PVS1 Very Strong: Null variant (frame-shift), in gene DNAJC21 for which loss-of-function is a known mechanism of disease (gene has 9 pathogenic LOF variants and gnomAD Loss-of-Function Observed/Expected = 0.48 is less than 0.755), associated with Bone marrow failure syndrome 3. PM2 Moderate: Variant not found in gnomAD exomes. Variant not found in gnomAD genomes (good gnomAD genomes coverage = 31.6).
