Genes affected

ALDH6A1 (HGNC:7179): (aldehyde dehydrogenase 6 family member A1) This gene encodes a member of the aldehyde dehydrogenase protein family. The encoded protein is a mitochondrial methylmalonate semialdehyde dehydrogenase that plays a role in the valine and pyrimidine catabolic pathways. This protein catalyzes the irreversible oxidative decarboxylation of malonate and methylmalonate semialdehydes to acetyl- and propionyl-CoA. Methylmalonate semialdehyde dehydrogenase deficiency is characterized by elevated beta-alanine, 3-hydroxypropionic acid, and both isomers of 3-amino and 3-hydroxyisobutyric acids in urine organic acids. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Jun 2013]

BBOF1 (HGNC:19855): (basal body orientation factor 1) Predicted to be involved in motile cilium assembly. Predicted to be located in ciliary basal body. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.8).
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00542 (825/152106) while in subpopulation AFR AF = 0.0193 (800/41490). AF 95% confidence interval is 0.0182. There are 9 homozygotes in GnomAd4. There are 381 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 9 AR gene
