Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 01, 2024The c.427C>T (p.R143C) alteration is located in exon 5 (coding exon 4) of the CHID1 gene. This alteration results from a C to T substitution at nucleotide position 427, causing the arginine (R) at amino acid position 143 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
