Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 07, 2023The c.29C>T (p.T10I) alteration is located in exon 1 (coding exon 1) of the SMC5 gene. This alteration results from a C to T substitution at nucleotide position 29, causing the threonine (T) at amino acid position 10 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
