Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_152781.4(HEATR9):ā€‹c.1653A>Gā€‹(p.Ile551Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,892 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/18 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I551T) has been classified as Likely benign.

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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 19, 2022The c.1653A>G (p.I551M) alteration is located in exon 15 (coding exon 15) of the HEATR9 gene. This alteration results from a A to G substitution at nucleotide position 1653, causing the isoleucine (I) at amino acid position 551 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
