Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 02, 2022The c.515A>G (p.Q172R) alteration is located in exon 7 (coding exon 7) of the EQTN gene. This alteration results from a A to G substitution at nucleotide position 515, causing the glutamine (Q) at amino acid position 172 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
