Genes affected

ANKH (HGNC:15492): (ANKH inorganic pyrophosphate transport regulator) This gene encodes a multipass transmembrane protein that is expressed in joints and other tissues and controls pyrophosphate levels in cultured cells. Progressive ankylosis-mediated control of pyrophosphate levels has been suggested as a possible mechanism regulating tissue calcification and susceptibility to arthritis in higher animals. Mutations in this gene have been associated with autosomal dominant craniometaphyseal dysplasia. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

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

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.91).

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00185 (281/152130) while in subpopulation AFR AF = 0.00641 (266/41494). AF 95% confidence interval is 0.00578. There are 1 homozygotes in GnomAd4. There are 124 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High AC in GnomAd4 at 281 AD gene.
