Genes affected

RET (HGNC:9967): (ret proto-oncogene) This gene encodes a transmembrane receptor and member of the tyrosine protein kinase family of proteins. Binding of ligands such as GDNF (glial cell-line derived neurotrophic factor) and other related proteins to the encoded receptor stimulates receptor dimerization and activation of downstream signaling pathways that play a role in cell differentiation, growth, migration and survival. The encoded receptor is important in development of the nervous system, and the development of organs and tissues derived from the neural crest. This proto-oncogene can undergo oncogenic activation through both cytogenetic rearrangement and activating point mutations. Mutations in this gene are associated with Hirschsprung disease and central hypoventilation syndrome and have been identified in patients with renal agenesis. [provided by RefSeq, Sep 2017]

ACMG classification

Verdict is Benign. Variant got -9 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.78).
• BP6: Variant 10-43077222-G-C is Benign according to our data. Variant chr10-43077222-G-C is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 477374.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=2}.
• BS1: Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.0000395 (6/151978) while in subpopulation EAS AF= 0.000966 (5/5178). AF 95% confidence interval is 0.00038. There are 0 homozygotes in gnomad4. There are 2 alleles in male gnomad4 subpopulation. Median coverage is 35. This position pass quality control queck.

This variant occurs in a non-coding region of the RET gene. It does not change the encoded amino acid sequence of the RET protein. This variant is present in population databases (rs751005619, gnomAD 0.07%). This variant has been observed in individual(s) with Hirschsprung disease (PMID: 14633923). ClinVar contains an entry for this variant (Variation ID: 477374). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
