Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 09, 2021The c.721G>A (p.V241M) alteration is located in exon 3 (coding exon 2) of the MFAP3L gene. This alteration results from a G to A substitution at nucleotide position 721, causing the valine (V) at amino acid position 241 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
