Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 24, 2022The c.1730T>C (p.I577T) alteration is located in exon 5 (coding exon 4) of the TMEM168 gene. This alteration results from a T to C substitution at nucleotide position 1730, causing the isoleucine (I) at amino acid position 577 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
