Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2022The c.505G>A (p.G169R) alteration is located in exon 7 (coding exon 7) of the EQTN gene. This alteration results from a G to A substitution at nucleotide position 505, causing the glycine (G) at amino acid position 169 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
