Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 23, 2023The c.383C>T (p.S128L) alteration is located in exon 7 (coding exon 6) of the TMEM175 gene. This alteration results from a C to T substitution at nucleotide position 383, causing the serine (S) at amino acid position 128 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
