Genes affected

ZNF821 (HGNC:28043): (zinc finger protein 821) This gene encodes a protein with two C2H2 zinc finger motifs and a score-and-three (23)-amino acid peptide repeat (STPR) domain. The STPR domain of the encoded protein binds to double stranded DNA and may also contain a nuclear localization signal, suggesting that this protein interacts with chromosomal DNA. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Jan 2011]

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]

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]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.47).
