Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 25, 2024The c.2175G>C (p.W725C) alteration is located in exon 13 (coding exon 13) of the TMEM8A gene. This alteration results from a G to C substitution at nucleotide position 2175, causing the tryptophan (W) at amino acid position 725 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
