Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 22, 2024The c.797A>G (p.N266S) alteration is located in exon 6 (coding exon 6) of the MFAP1 gene. This alteration results from a A to G substitution at nucleotide position 797, causing the asparagine (N) at amino acid position 266 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
