RCV004690315 | SCV005185979 | likely benign | not specified | 2024-05-03 | criteria provided, single submitter | clinical testing | Variant summary: WDR11 c.2303_2304delinsTG (p.Ala768Val) results in a non-conservative amino acid change located in the WD40 repeat (IPR001680) of the encoded protein sequence. Three out of five in-silico tools predict a benign effect of the variant on protein function. The allele frequency of this variant could not be determined from population databases such as gnomAD as it is a multinucleotide variant consisting of 10-120889969-C-T (c.2303C>T; p.Ala768Val) and 10-120889970-A-G (c.2304A>G; p.Ala768=). The individual variants have variable frequencies and the exact number of alleles representing a combination of the two in cis is unknown. However, based on the frequency of the least prevalent allele, namely c.2303C>T, it can be estimated that the multinucleotide variant will be found at a frequency of 0.00051 in 1613846 control chromosomes, predominantly at a frequency of 0.0097 within the African or African-American subpopulation in gnomAD including 8 homozygotes. This strongly suggests that the variant could be a benign polymorphism found primarily in populations of African or African-American origin. c.2303_2304delinsTG has been reported in the literature in at least one individual affected with congenital hypogonadotropic hypogonadism without a strong evidence for causality (Abbara_2020). These report(s) do not provide unequivocal conclusions about association of the variant with hypogonadotropic hypogonadism 14 with or without anosmia. 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: 33227799, 32870266). ClinVar contains an entry for this variant (Variation ID: 1956714). Based on the evidence outlined above, the variant was classified as likely benign. |
