Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 17, 2023The c.1879C>T (p.R627W) alteration is located in exon 11 (coding exon 11) of the TMEM8A gene. This alteration results from a C to T substitution at nucleotide position 1879, causing the arginine (R) at amino acid position 627 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
