Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 21, 2024The c.56T>C (p.L19S) alteration is located in exon 4 (coding exon 2) of the TMEM108 gene. This alteration results from a T to C substitution at nucleotide position 56, causing the leucine (L) at amino acid position 19 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
