Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV005240506 SCV005886956 uncertain significance not specified 2025-01-31 criteria provided, single submitter clinical testing Variant summary: TSPEAR c.1852T>A (p.Tyr618Asn) results in a non-conservative amino acid change located in the EAR repeat domain (IPR009039) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 2e-05 in 251280 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.1852T>A has been reported in the literature in one individual affected with Ectodermal Dysplasia and the 2ed variant appeared to be likely benign (Peled_2016) . These report(s) do not provide unequivocal conclusions about association of the variant with Ectodermal Dysplasia 14, Hair/tooth Type With Or Without Hypohidrosis. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication has been ascertained in the context of this evaluation (PMID: 27736875). ClinVar contains an entry for this variant (Variation ID: 590273). Based on the evidence outlined above, the variant was classified as uncertain significance.
