Genes affected

PIEZO2 (HGNC:26270): (piezo type mechanosensitive ion channel component 2) The protein encoded by this gene contains more than thirty transmembrane domains and likely functions as part of mechanically-activated (MA) cation channels. These channels serve to connect mechanical forces to biological signals. The encoded protein quickly adapts MA currents in somatosensory neurons. Defects in this gene are a cause of type 5 distal arthrogryposis. Several alternatively spliced transcript variants of this gene have been described, but their full-length nature is not known.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.1295436).

BP6

Variant 18-10705418-C-T is Benign according to our data. Variant chr18-10705418-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 521522.

BS1

Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.0000267 (37/1384938) while in subpopulation AMR AF = 0.000952 (34/35700). AF 95% confidence interval is 0.0007. There are 0 homozygotes in GnomAdExome4. There are 14 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.
