Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 12, 2024The c.1222G>A (p.G408S) alteration is located in exon 14 (coding exon 13) of the CHID1 gene. This alteration results from a G to A substitution at nucleotide position 1222, causing the glycine (G) at amino acid position 408 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
