Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 08, 2024The c.61G>A (p.A21T) alteration is located in exon 1 (coding exon 1) of the CNTD1 gene. This alteration results from a G to A substitution at nucleotide position 61, causing the alanine (A) at amino acid position 21 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
