Genes affected

CRYBG1 (HGNC:356): (crystallin beta-gamma domain containing 1) Predicted to enable carbohydrate binding activity. [provided by Alliance of Genome Resources, Apr 2022]

RTN4IP1 (HGNC:18647): (reticulon 4 interacting protein 1) This gene encodes a mitochondrial protein that interacts with reticulon 4, which is a potent inhibitor of regeneration following spinal cord injury. This interaction may be important for reticulon-induced inhibition of neurite growth. Mutations in this gene can cause optic atrophy 10, with or without ataxia, cognitive disability, and seizures. There is a pseudogene for this gene on chromosome 12. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

• optic atrophy 10 with or without ataxia, intellectual disability, and seizures

  Inheritance: AR Classification: DEFINITIVE, STRONG, MODERATE Submitted by: Labcorp Genetics (formerly Invitae), Ambry Genetics, G2P
• autosomal recessive optic atrophy

  Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Benign. The variant received -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.94).
• BP6: Variant 6-106571760-A-G is Benign according to our data. Variant chr6-106571760-A-G is described in ClinVar as Benign. ClinVar VariationId is 1228467.Status of the report is criteria_provided_single_submitter, 1 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.203 is higher than 0.05.
