Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 09, 2024The c.665C>T (p.P222L) alteration is located in exon 5 (coding exon 5) of the TMEM183A gene. This alteration results from a C to T substitution at nucleotide position 665, causing the proline (P) at amino acid position 222 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
