Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 18, 2022The c.85A>C (p.K29Q) alteration is located in exon 1 (coding exon 1) of the MCEMP1 gene. This alteration results from a A to C substitution at nucleotide position 85, causing the lysine (K) at amino acid position 29 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
