RCV003994669 | SCV004812557 | uncertain significance | Hearing loss, autosomal dominant 80 | 2024-02-05 | criteria provided, single submitter | clinical testing | This sequence change in GREB1L is predicted to replace serine with phenylalanine at codon 228, p.(Ser228Phe). The serine residue is moderately conserved (100 vertebrates, Multiz Alignments), and is located in a region of the GREB1 N-terminal domain that is highly intolerant to missense variation (amino acids 227-229). There is a large physicochemical difference between serine and phenylalanine. The highest population minor allele frequency in the population database gnomAD v4.0 is 0.0002% (2/1,078,756 alleles) in the European (non-Finnish) population, which is consistent with autosomal dominant deafness. To our knowledge, this variant has not been previously reported in the relevant scientific literature or databases. Computational evidence predicts a benign effect for the missense substitution (REVEL = 0.147). Based on the classification scheme RMH Modified ACMG/AMP Guidelines v1.6.1, this variant is classified as a VARIANT OF UNCERTAIN SIGNIFICANCE. Following criteria are met: PM1, PM2_Supporting, BP4. |
