Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 02, 2024The c.508G>A (p.A170T) alteration is located in exon 5 (coding exon 4) of the MIDN gene. This alteration results from a G to A substitution at nucleotide position 508, causing the alanine (A) at amino acid position 170 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
