Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 24, 2023The c.1883T>A (p.L628H) alteration is located in exon 11 (coding exon 11) of the TMEM8A gene. This alteration results from a T to A substitution at nucleotide position 1883, causing the leucine (L) at amino acid position 628 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
