RCV001819979 | SCV002070101 | uncertain significance | not specified | 2020-01-16 | criteria provided, single submitter | clinical testing | DNA sequence analysis of the WT1 gene demonstrated a sequence change, c.1334A>G, in exon 8 that results in an amino acid change, p.His445Arg. This sequence change has been previously described in a patient who presented with ambiguous genitalia (enlarged clitoris and labia majora) and large echogenic kidneys, supporting the diagnosis of e Denys-Drash syndrome (DDS)–Frasier syndrome spectrum (NeoReviews August 2018, 19 (8) e485-e489). This sequence change has not been reported in the large population databases (ExAC and gnomAD). The p.His445Arg change affects a highly conserved amino acid residue located in a domain of the WT1 protein that is known to be functional. In-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL) provide contradictory results for the p.His445Arg substitution. Due to these contrasting evidences and the lack of functional studies, the clinical significance of the p.His445Arg change remains unknown at this time. |
