Genes affected
FERRY3 (HGNC:1184): (FERRY endosomal RAB5 effector complex subunit 3) This gene is highly conserved from nematodes to humans. In rat, the orthologous gene encodes a cytoplasmic protein that is involved in mast cell degranulation. The human gene has been implicated in autosomal recessive intellectual disability. [provided by RefSeq, Sep 2016]
FERRY3 Gene-Disease associations (from GenCC):
  • intellectual disability, autosomal recessive 66

Significance:Pathogenic
Review Status:criteria provided, single submitter
Collection Method:clinical testing

Stop-gained (nonsense): predicted to result in a loss or disruption of normal protein function through nonsense-mediated decay (NMD) or protein truncation. Multiple pathogenic variants are reported downstream of the variant (PVS1_VS).The variant has been reported at least twice as pathogenic/likely pathogenic with clinical assertions and evidence for the classification (ClinVar ID: VCV000592164, PMID:28097321). It is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.000025, PM2_M). Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline. -
