Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 17, 2023The c.2032G>A (p.G678R) alteration is located in exon 13 (coding exon 13) of the TMEM8A gene. This alteration results from a G to A substitution at nucleotide position 2032, causing the glycine (G) at amino acid position 678 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
