Genes affected

HEATR9 (HGNC:26548): (HEAT repeat containing 9) Predicted to act upstream of or within hematopoietic progenitor cell differentiation. [provided by Alliance of Genome Resources, Apr 2022]

TAF15 (HGNC:11547): (TATA-box binding protein associated factor 15) This gene encodes a member of the TET family of RNA-binding proteins. The encoded protein plays a role in RNA polymerase II gene transcription as a component of a distinct subset of multi-subunit transcription initiation factor TFIID complexes. Translocations involving this gene play a role in acute leukemia and extraskeletal myxoid chondrosarcoma, and mutations in this gene may play a role in amyotrophic lateral sclerosis. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, May 2012]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.11021778).

The c.636T>G (p.N212K) alteration is located in exon 8 (coding exon 8) of the HEATR9 gene. This alteration results from a T to G substitution at nucleotide position 636, causing the asparagine (N) at amino acid position 212 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
