Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 20, 2021The c.255A>T (p.R85S) alteration is located in exon 3 (coding exon 3) of the EQTN gene. This alteration results from a A to T substitution at nucleotide position 255, causing the arginine (R) at amino acid position 85 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
