Genes affected

RARA (HGNC:9864): (retinoic acid receptor alpha) This gene represents a nuclear retinoic acid receptor. The encoded protein, retinoic acid receptor alpha, regulates transcription in a ligand-dependent manner. This gene has been implicated in regulation of development, differentiation, apoptosis, granulopoeisis, and transcription of clock genes. Translocations between this locus and several other loci have been associated with acute promyelocytic leukemia. Alternatively spliced transcript variants have been found for this locus.[provided by RefSeq, Sep 2010]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.56).
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0151 (2298/152282) while in subpopulation NFE AF= 0.0228 (1548/68002). AF 95% confidence interval is 0.0218. There are 29 homozygotes in gnomad4. There are 1139 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High AC in GnomAd at 2299 AD gene.
