RCV004586995 | SCV005076588 | benign | not specified | 2024-04-24 | criteria provided, single submitter | clinical testing | Variant summary: CORO1A c.451+8G>A alters a non-conserved nucleotide located close to a canonical splice site and therefore could affect mRNA splicing, leading to a significantly altered protein sequence. Consensus agreement among computation tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.00036 in 249090 control chromosomes, predominantly at a frequency of 0.0044 within the African or African-American subpopulation in the gnomAD database. The observed variant frequency within African or African-American control individuals in the gnomAD database is approximately 12.45 fold of the estimated maximal expected allele frequency for a pathogenic variant in CORO1A causing Severe Combined Immunodeficiency phenotype (0.00035), strongly suggesting that the variant is a benign polymorphism found primarily in populations of African or African-American origin. To our knowledge, no occurrence of c.451+8G>A in individuals affected with Severe Combined Immunodeficiency and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 791759). Based on the evidence outlined above, the variant was classified as benign. |
