Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 06, 2021The c.1690C>A (p.L564I) alteration is located in exon 16 (coding exon 16) of the MIGA1 gene. This alteration results from a C to A substitution at nucleotide position 1690, causing the leucine (L) at amino acid position 564 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
