Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 03, 2024The c.2287G>T (p.D763Y) alteration is located in exon 13 (coding exon 13) of the TMEM8A gene. This alteration results from a G to T substitution at nucleotide position 2287, causing the aspartic acid (D) at amino acid position 763 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
