Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 06, 2023The c.227A>T (p.K76M) alteration is located in exon 4 (coding exon 3) of the CCDC171 gene. This alteration results from a A to T substitution at nucleotide position 227, causing the lysine (K) at amino acid position 76 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
