Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 26, 2024The c.1127T>C (p.L376P) alteration is located in exon 7 (coding exon 7) of the TMEM143 gene. This alteration results from a T to C substitution at nucleotide position 1127, causing the leucine (L) at amino acid position 376 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
