Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 21, 2023The c.928A>T (p.I310F) alteration is located in exon 2 (coding exon 1) of the TMEM168 gene. This alteration results from a A to T substitution at nucleotide position 928, causing the isoleucine (I) at amino acid position 310 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
