Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 09, 2024The c.176G>A (p.R59Q) alteration is located in exon 1 (coding exon 1) of the MGAT5B gene. This alteration results from a G to A substitution at nucleotide position 176, causing the arginine (R) at amino acid position 59 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
