Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 18, 2024The c.473C>G (p.P158R) alteration is located in exon 4 (coding exon 2) of the TMEM108 gene. This alteration results from a C to G substitution at nucleotide position 473, causing the proline (P) at amino acid position 158 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
