Therefore, it has been classified as a Variant of Uncertain Significance. A similar duplication has been observed in individual(s) with clinical features of HRAS-related conditions (PMID: 29684080). This variant is a gross deletion of the genomic region encompassing exon(s) 2-4 of the HRAS gene, which includes the initiator codon. The 5' end of this event is unknown as it extends beyond the assayed region for this gene and therefore may encompass additional genes. The 3' boundary is likely confined to intron 4 of the HRAS gene. It is expected to result in an absent or disrupted protein product. However, the current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in HRAS cause disease.
