Genes affected

HRAS (HGNC:5173): (HRas proto-oncogene, GTPase) This gene belongs to the Ras oncogene family, whose members are related to the transforming genes of mammalian sarcoma retroviruses. The products encoded by these genes function in signal transduction pathways. These proteins can bind GTP and GDP, and they have intrinsic GTPase activity. This protein undergoes a continuous cycle of de- and re-palmitoylation, which regulates its rapid exchange between the plasma membrane and the Golgi apparatus. Mutations in this gene cause Costello syndrome, a disease characterized by increased growth at the prenatal stage, growth deficiency at the postnatal stage, predisposition to tumor formation, cognitive disability, skin and musculoskeletal abnormalities, distinctive facial appearance and cardiovascular abnormalities. Defects in this gene are implicated in a variety of cancers, including bladder cancer, follicular thyroid cancer, and oral squamous cell carcinoma. Multiple transcript variants, which encode different isoforms, have been identified for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -8 ACMG points.

PM1

In a chain GTPase HRas, N-terminally processed (size 184) in uniprot entity RASH_HUMAN there are 12 pathogenic changes around while only 2 benign (86%) in NM_005343.4

BP4

Computational evidence support a benign effect (MetaRNN=0.4155776).

BP6

Variant 11-532746-C-T is Benign according to our data. Variant chr11-532746-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 40445.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=2, Uncertain_significance=1}.

BS1

Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.0000116 (17/1460486) while in subpopulation AMR AF= 0.000201 (9/44722). AF 95% confidence interval is 0.000104. There are 0 homozygotes in gnomad4_exome. There are 8 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck.

BS2

High AC in GnomAd4 at 5 AD gene.
