Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 16, 2021The c.1127C>G (p.T376R) alteration is located in exon 8 (coding exon 8) of the AMDHD2 gene. This alteration results from a C to G substitution at nucleotide position 1127, causing the threonine (T) at amino acid position 376 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
