Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 22, 2021The c.259A>C (p.I87L) alteration is located in exon 4 (coding exon 3) of the TMEM175 gene. This alteration results from a A to C substitution at nucleotide position 259, causing the isoleucine (I) at amino acid position 87 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
