Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 17, 2024The c.1471C>T (p.H491Y) alteration is located in exon 6 (coding exon 5) of the CCDC181 gene. This alteration results from a C to T substitution at nucleotide position 1471, causing the histidine (H) at amino acid position 491 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
