not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 23, 2024The c.2758G>A (p.A920T) alteration is located in exon 18 (coding exon 17) of the CCDC158 gene. This alteration results from a G to A substitution at nucleotide position 2758, causing the alanine (A) at amino acid position 920 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
