Genes affected

AMACR (HGNC:451): (alpha-methylacyl-CoA racemase) This gene encodes a racemase. The encoded enzyme interconverts pristanoyl-CoA and C27-bile acylCoAs between their (R)- and (S)-stereoisomers. The conversion to the (S)-stereoisomers is necessary for degradation of these substrates by peroxisomal beta-oxidation. Encoded proteins from this locus localize to both mitochondria and peroxisomes. Mutations in this gene may be associated with adult-onset sensorimotor neuropathy, pigmentary retinopathy, and adrenomyeloneuropathy due to defects in bile acid synthesis. Alternatively spliced transcript variants have been described. Read-through transcription also exists between this gene and the upstream neighboring C1QTNF3 (C1q and tumor necrosis factor related protein 3) gene. [provided by RefSeq, Mar 2011]

C1QTNF3-AMACR (HGNC:49198): (C1QTNF3-AMACR readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring C1q and tumor necrosis factor related protein 3 (C1QTNF3) and alpha-methylacyl-CoA racemase (AMACR) genes on chromosome 5. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is thus not likely to produce a protein product. [provided by RefSeq, Mar 2011]

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.98).
• BP6: Variant 5-33988117-C-T is Benign according to our data. Variant chr5-33988117-C-T is described in ClinVar as Likely_benign. ClinVar VariationId is 353240.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.00852 (1297/152302) while in subpopulation SAS AF = 0.0313 (151/4826). AF 95% confidence interval is 0.0272. There are 10 homozygotes in GnomAd4. There are 662 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 10 AR gene
