Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 26, 2024The c.389T>C (p.I130T) alteration is located in exon 2 (coding exon 2) of the TMEM178B gene. This alteration results from a T to C substitution at nucleotide position 389, causing the isoleucine (I) at amino acid position 130 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
