The c.1012G>A (p.A338T) alteration is located in exon 10 (coding exon 7) of the CCDC36 gene. This alteration results from a G to A substitution at nucleotide position 1012, causing the alanine (A) at amino acid position 338 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
