Uncertain significance, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Aug 14, 2023 | Variant summary: SPRED1 c.182G>A (p.Arg61His) results in a non-conservative amino acid change located in the WH1/EVH1 domain (IPR000697) of the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 2e-05 in 251124 control chromosomes (i.e., 5 heterozygotes; gnomAD v2.1 Exomes dataset). Although the available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance, the allele frequency in controls is not suggestive of highly penetrant variant responsible for autosomal dominant disease. c.182G>A has been reported in the literature in individuals affected psoriasis, including one de novo occurrence (e.g., Li_JAutoimmun_2020 and Li_JDermatol_2020). Additionally, the variant was identified in an individual with Noonan syndrome, however authors classified this variant as likely benign due to a co-occurring pathogenic PTPN11 variant (Lodi_2020). These reports therefore do not provide unequivocal conclusions about association of the variant with Neurofibromatosis Type 1-Like Syndrome (Legius Syndrome). Co-occurrences with other pathogenic variants have been observed (PTPN11 c.922A>G, p.Asn308Asp, Lodi_2020; PTPN11 c.1510A>G, p.Met504Val, Internal testing), providing supporting evidence for a benign role. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 31629629, 32396270, 32806529). One submitter has reported clinical-significance assessments for this variant to ClinVar after 2014 and has classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as VUS-possibly benign. - |
Legius syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Aug 29, 2023 | This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 61 of the SPRED1 protein (p.Arg61His). This variant is present in population databases (rs750686148, gnomAD 0.008%). This missense change has been observed in individual(s) with psoriasis (PMID: 31629629). ClinVar contains an entry for this variant (Variation ID: 468794). Advanced modeling performed at Invitae incorporating data from internal and/or published experimental studies (Invitae) indicates that this missense variant is not expected to disrupt SPRED1 function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
