The c.634G>T (p.D212Y) alteration is located in exon 8 (coding exon 7) of the CHID1 gene. This alteration results from a G to T substitution at nucleotide position 634, causing the aspartic acid (D) at amino acid position 212 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
