Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 02, 2023The c.12A>G (p.I4M) alteration is located in exon 1 (coding exon 1) of the EQTN gene. This alteration results from a A to G substitution at nucleotide position 12, causing the isoleucine (I) at amino acid position 4 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
