Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 02, 2024The c.503C>T (p.T168I) alteration is located in exon 6 (coding exon 5) of the TMEM71 gene. This alteration results from a C to T substitution at nucleotide position 503, causing the threonine (T) at amino acid position 168 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
