Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2024The c.467T>C (p.L156P) alteration is located in exon 8 (coding exon 7) of the TMEM175 gene. This alteration results from a T to C substitution at nucleotide position 467, causing the leucine (L) at amino acid position 156 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
