Genes affected

ATXN1L (HGNC:33279): (ataxin 1 like) Predicted to enable DNA binding activity and RNA binding activity. Predicted to be involved in several processes, including learning or memory; regulation of transcription, DNA-templated; and social behavior. Predicted to act upstream of or within several processes, including lung alveolus development; negative regulation of transcription by RNA polymerase II; and positive regulation of hematopoietic stem cell proliferation. Located in nucleolus and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

IST1 (HGNC:28977): (IST1 factor associated with ESCRT-III) This gene encodes a protein with MIT-interacting motifs that interacts with components of endosomal sorting complexes required for transport (ESCRT). ESCRT functions in vesicle budding, such as that which occurs during membrane abscission in cytokinesis. There is a pseudogene for this gene on chromosome 19. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Aug 2012]

ACMG classification

Our verdict: Likely_benign. The variant received -6 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.12896821).
• BS2: High AC in GnomAdExome4 at 24 AD gene.
