Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 17, 2023The c.550A>G (p.K184E) alteration is located in exon 3 (coding exon 2) of the MFAP3L gene. This alteration results from a A to G substitution at nucleotide position 550, causing the lysine (K) at amino acid position 184 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
