Genes affected

ANK1 (HGNC:492): (ankyrin 1) Ankyrins are a family of proteins that link the integral membrane proteins to the underlying spectrin-actin cytoskeleton and play key roles in activities such as cell motility, activation, proliferation, contact and the maintenance of specialized membrane domains. Multiple isoforms of ankyrin with different affinities for various target proteins are expressed in a tissue-specific, developmentally regulated manner. Most ankyrins are typically composed of three structural domains: an amino-terminal domain containing multiple ankyrin repeats; a central region with a highly conserved spectrin binding domain; and a carboxy-terminal regulatory domain which is the least conserved and subject to variation. Ankyrin 1, the prototype of this family, was first discovered in the erythrocytes, but since has also been found in brain and muscles. Mutations in erythrocytic ankyrin 1 have been associated in approximately half of all patients with hereditary spherocytosis. Complex patterns of alternative splicing in the regulatory domain, giving rise to different isoforms of ankyrin 1 have been described. Truncated muscle-specific isoforms of ankyrin 1 resulting from usage of an alternate promoter have also been identified. [provided by RefSeq, Dec 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.87).

BP6

Variant 8-41661785-G-A is Benign according to our data. Variant chr8-41661785-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 261318.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00804 (1225/152306) while in subpopulation NFE AF = 0.00894 (608/68032). AF 95% confidence interval is 0.00835. There are 12 homozygotes in GnomAd4. There are 676 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2
