Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 12, 2024The c.667T>C (p.F223L) alteration is located in exon 5 (coding exon 5) of the TMEM143 gene. This alteration results from a T to C substitution at nucleotide position 667, causing the phenylalanine (F) at amino acid position 223 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
