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

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), RARA. . Gene score misZ 3.0806 (greater than the threshold 3.09). Trascript score misZ 3.3831 (greater than threshold 3.09). GenCC has associacion of gene with acute promyelocytic leukemia, multiple congenital anomalies/dysmorphic syndrome.

BP4

Computational evidence support a benign effect (MetaRNN=0.3786124).

The c.464A>G (p.K155R) alteration is located in exon 4 (coding exon 3) of the RARA gene. This alteration results from a A to G substitution at nucleotide position 464, causing the lysine (K) at amino acid position 155 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
