The c.205T>C (p.Y69H) alteration is located in exon 1 (coding exon 1) of the TMEM64 gene. This alteration results from a T to C substitution at nucleotide position 205, causing the tyrosine (Y) at amino acid position 69 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
