Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 13, 2023The c.566G>A (p.R189K) alteration is located in exon 3 (coding exon 2) of the MFAP3 gene. This alteration results from a G to A substitution at nucleotide position 566, causing the arginine (R) at amino acid position 189 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
