Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 07, 2023The c.864C>G (p.N288K) alteration is located in exon 8 (coding exon 8) of the EQTN gene. This alteration results from a C to G substitution at nucleotide position 864, causing the asparagine (N) at amino acid position 288 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
