Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 31, 2024The c.28C>G (p.H10D) alteration is located in exon 2 (coding exon 1) of the CMC2 gene. This alteration results from a C to G substitution at nucleotide position 28, causing the histidine (H) at amino acid position 10 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
