The c.22T>G (p.Y8D) alteration is located in exon 2 (coding exon 1) of the BTBD10 gene. This alteration results from a T to G substitution at nucleotide position 22, causing the tyrosine (Y) at amino acid position 8 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
