Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 27, 2024The c.1244C>G (p.T415R) alteration is located in exon 9 (coding exon 9) of the MAN1A2 gene. This alteration results from a C to G substitution at nucleotide position 1244, causing the threonine (T) at amino acid position 415 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
