Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 20, 2024The c.215A>G (p.Q72R) alteration is located in exon 1 (coding exon 1) of the MCTP2 gene. This alteration results from a A to G substitution at nucleotide position 215, causing the glutamine (Q) at amino acid position 72 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
