Genes affected

EDNRA (HGNC:3179): (endothelin receptor type A) This gene encodes the receptor for endothelin-1, a peptide that plays a role in potent and long-lasting vasoconstriction. This receptor associates with guanine-nucleotide-binding (G) proteins, and this coupling activates a phosphatidylinositol-calcium second messenger system. Polymorphisms in this gene have been linked to migraine headache resistance. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2009]

EDNRA (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), EDNRA. . Gene score misZ 2.8025 (greater than the threshold 3.09). Trascript score misZ 3.9779 (greater than threshold 3.09). GenCC has associacion of gene with mandibulofacial dysostosis with alopecia.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.827
• PP5: Variant 4-147539823-G-A is Pathogenic according to our data. Variant chr4-147539823-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 190324.Status of the report is no_assertion_criteria_provided, 0 stars.
