Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 11, 2024The c.76G>C (p.A26P) alteration is located in exon 1 (coding exon 1) of the TACO1 gene. This alteration results from a G to C substitution at nucleotide position 76, causing the alanine (A) at amino acid position 26 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
