Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 31, 2023The c.175C>G (p.L59V) alteration is located in exon 2 (coding exon 2) of the TMEM170A gene. This alteration results from a C to G substitution at nucleotide position 175, causing the leucine (L) at amino acid position 59 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
