Genes affected
ANO6 (HGNC:25240): (anoctamin 6) This gene encodes a multi-pass transmembrane protein that belongs to the anoctamin family. This protein is an essential component for the calcium-dependent exposure of phosphatidylserine on the cell surface. The scrambling of phospholipid occurs in various biological systems, such as when blood platelets are activated, they expose phosphatidylserine to trigger the clotting system. Mutations in this gene are associated with Scott syndrome. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Mar 2011]

Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00049 in 1606956 control chromosomes, predominantly at a frequency of 0.0092 within the African or African-American subpopulation in the gnomAD database, including 1 homozygote. To our knowledge, no occurrence of c.94A>T in individuals affected with Scott Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 2051043). Based on the evidence outlined above, the variant was classified as benign. -
